Sync contrib/tools/python3 layout with upstream

* Move src/ subdir contents to the top of the layout
* Rename self-written lib -> lib2 to avoid CaseFolding warning from the VCS
* Regenerate contrib/libs/python proxy-headers accordingly

+     the "overflowed" flag in the thread state structure. This flag

+   * "last chance" anti-recursion protection is triggered when the recursion
+     level exceeds "current recursion limit + 50". By construction, this

+     means the cleanup code has itself gone into an infinite loop, or the
+     RecursionError has been mistakingly ignored. When this protection is
+     triggered, the interpreter aborts with a Fatal Error.
+
+   In addition, the "overflowed" flag is automatically reset when the
+   recursion level drops below "current recursion limit - 50". This heuristic
+   is meant to ensure that the normal anti-recursion protection doesn't get
+   disabled too long.
+

+   sets of parameters: one set for 30-bit digits, stored in an unsigned 32-bit
+   integer type, and one set for 15-bit digits with each digit stored in an
+   unsigned short.  The value of PYLONG_BITS_IN_DIGIT, defined either at
+   configure time or in pyport.h, is used to decide which digit size to use.
+
+   Type 'digit' should be able to hold 2*PyLong_BASE-1, and type 'twodigits'
+   should be an unsigned integer type able to hold all integers up to
+   PyLong_BASE*PyLong_BASE-1.  x_sub assumes that 'digit' is an unsigned type,
+   and that overflow is handled by taking the result modulo 2**N for some N >
+   PyLong_SHIFT.  The majority of the code doesn't care about the precise
+   value of PyLong_SHIFT, but there are some notable exceptions:
+
+   - PyLong_{As,From}ByteArray require that PyLong_SHIFT be at least 8
+
+   - long_hash() requires that PyLong_SHIFT is *strictly* less than the number
+     of bits in an unsigned long, as do the PyLong <-> long (or unsigned long)
+     conversion functions
+
+   - the Python int <-> size_t/Py_ssize_t conversion functions expect that
+     PyLong_SHIFT is strictly less than the number of bits in a size_t
+
+   - the marshal code currently expects that PyLong_SHIFT is a multiple of 15
+
+   - NSMALLNEGINTS and NSMALLPOSINTS should be small enough to fit in a single
+     digit; with the current values this forces PyLong_SHIFT >= 9
+
+  The values 15 and 30 should fit all of the above requirements, on any
+  platform.

+/* Trashcan mechanism, thanks to Christian Tismer.
+
+When deallocating a container object, it's possible to trigger an unbounded
+chain of deallocations, as each Py_DECREF in turn drops the refcount on "the
+next" object in the chain to 0.  This can easily lead to stack overflows,
+especially in threads (which typically have less stack space to work with).
+
+A container object can avoid this by bracketing the body of its tp_dealloc
+function with a pair of macros:
+
+static void
+mytype_dealloc(mytype *p)
+{
+    ... declarations go here ...
+
+    PyObject_GC_UnTrack(p);        // must untrack first
+    Py_TRASHCAN_BEGIN(p, mytype_dealloc)
+    ... The body of the deallocator goes here, including all calls ...
+    ... to Py_DECREF on contained objects.                         ...
+    Py_TRASHCAN_END                // there should be no code after this
+}
+
+CAUTION:  Never return from the middle of the body!  If the body needs to
+"get out early", put a label immediately before the Py_TRASHCAN_END
+call, and goto it.  Else the call-depth counter (see below) will stay
+above 0 forever, and the trashcan will never get emptied.
+
+How it works:  The BEGIN macro increments a call-depth counter.  So long
+as this counter is small, the body of the deallocator is run directly without
+further ado.  But if the counter gets large, it instead adds p to a list of
+objects to be deallocated later, skips the body of the deallocator, and
+resumes execution after the END macro.  The tp_dealloc routine then returns
+without deallocating anything (and so unbounded call-stack depth is avoided).
+
+When the call stack finishes unwinding again, code generated by the END macro
+notices this, and calls another routine to deallocate all the objects that
+may have been added to the list of deferred deallocations.  In effect, a
+chain of N deallocations is broken into (N-1)/(_PyTrash_UNWIND_LEVEL-1) pieces,
+with the call stack never exceeding a depth of _PyTrash_UNWIND_LEVEL.
+
+Since the tp_dealloc of a subclass typically calls the tp_dealloc of the base
+class, we need to ensure that the trashcan is only triggered on the tp_dealloc
+of the actual class being deallocated. Otherwise we might end up with a
+partially-deallocated object. To check this, the tp_dealloc function must be
+passed as second argument to Py_TRASHCAN_BEGIN().

+// The _PyTime_t API is written to use timestamp and timeout values stored in
+// various formats and to read clocks.
+//
+// The _PyTime_t type is an integer to support directly common arithmetic
+// operations like t1 + t2.
+//
+// The _PyTime_t API supports a resolution of 1 nanosecond. The _PyTime_t type
+// is signed to support negative timestamps. The supported range is around
+// [-292.3 years; +292.3 years]. Using the Unix epoch (January 1st, 1970), the
+// supported date range is around [1677-09-21; 2262-04-11].
+//
+// Formats:
+//
+// * seconds
+// * seconds as a floating pointer number (C double)
+// * milliseconds (10^-3 seconds)
+// * microseconds (10^-6 seconds)
+// * 100 nanoseconds (10^-7 seconds)
+// * nanoseconds (10^-9 seconds)
+// * timeval structure, 1 microsecond resolution (10^-6 seconds)
+// * timespec structure, 1 nanosecond resolution (10^-9 seconds)
+//
+// Integer overflows are detected and raise OverflowError. Conversion to a
+// resolution worse than 1 nanosecond is rounded correctly with the requested
+// rounding mode. There are 4 rounding modes: floor (towards -inf), ceiling
+// (towards +inf), half even and up (away from zero).
+//
+// Some functions clamp the result in the range [_PyTime_MIN; _PyTime_MAX], so
+// the caller doesn't have to handle errors and doesn't need to hold the GIL.
+// For example, _PyTime_Add(t1, t2) computes t1+t2 and clamp the result on
+// overflow.
+//
+// Clocks:
+//
+// * System clock
+// * Monotonic clock
+// * Performance counter
+//
+// Operations like (t * k / q) with integers are implemented in a way to reduce
+// the risk of integer overflow. Such operation is used to convert a clock
+// value expressed in ticks with a frequency to _PyTime_t, like
+// QueryPerformanceCounter() with QueryPerformanceFrequency().

+/* This file defines dynamic annotations for use with dynamic analysis
+   tool such as valgrind, PIN, etc.
+
+   Dynamic annotation is a source code annotation that affects
+   the generated code (that is, the annotation is not a comment).
+   Each such annotation is attached to a particular
+   instruction and/or to a particular object (address) in the program.
+
+   The annotations that should be used by users are macros in all upper-case
+   (e.g., _Py_ANNOTATE_NEW_MEMORY).
+
+   Actual implementation of these macros may differ depending on the
+   dynamic analysis tool being used.
+
+   See https://code.google.com/p/data-race-test/  for more information.
+
+   This file supports the following dynamic analysis tools:
+   - None (DYNAMIC_ANNOTATIONS_ENABLED is not defined or zero).
+      Macros are defined empty.
+   - ThreadSanitizer, Helgrind, DRD (DYNAMIC_ANNOTATIONS_ENABLED is 1).
+      Macros are defined as calls to non-inlinable empty functions
+      that are intercepted by Valgrind. */

+     Annotations useful when implementing condition variables such as CondVar,

+
+     The annotations _Py_ANNOTATE_HAPPENS_BEFORE() and
+     _Py_ANNOTATE_HAPPENS_AFTER() can be used to define happens-before arcs in
+     user-defined synchronization mechanisms: the race detector will infer an
+     arc from the former to the latter when they share the same argument
+     pointer.
+
+     Example 1 (reference counting):

+     void Unref() {
+       _Py_ANNOTATE_HAPPENS_BEFORE(&refcount_);
+       if (AtomicDecrementByOne(&refcount_) == 0) {

+         delete this;
+       }
+     }
+
+     Example 2 (message queue):
+
+     void MyQueue::Put(Type *e) {
+       MutexLock lock(&mu_);
+       _Py_ANNOTATE_HAPPENS_BEFORE(e);

+       _Py_ANNOTATE_HAPPENS_AFTER(e);

+        stream->next_out:  point to the next output position.
+        stream->avail_out: the number of available bytes left in the buffer.
+
+   It maintains a list of bytes object, so there is no overhead of resizing

+
+   Usage:
+
+   1, Initialize the struct instance like this:
+        _BlocksOutputBuffer buffer = {.list = NULL};
+      Set .list to NULL for _BlocksOutputBuffer_OnError()
+

+        _BlocksOutputBuffer_InitWithSize()
+
+   3, If (avail_out == 0), grow the buffer:
+        _BlocksOutputBuffer_Grow()
+
+   4, Get the current outputted data size:
+        _BlocksOutputBuffer_GetDataSize()
+
+   5, Finish the buffer, and return a bytes object:

+   NOTE: about untracking of mutable objects.
+
+   Certain types of container cannot participate in a reference cycle, and
+   so do not need to be tracked by the garbage collector. Untracking these
+   objects reduces the cost of garbage collections. However, determining
+   which objects may be untracked is not free, and the costs must be
+   weighed against the benefits for garbage collection.
+
+   There are two possible strategies for when to untrack a container:
+
+   i) When the container is created.
+   ii) When the container is examined by the garbage collector.
+
+   Tuples containing only immutable objects (integers, strings etc, and
+   recursively, tuples of immutable objects) do not need to be tracked.
+   The interpreter creates a large number of tuples, many of which will
+   not survive until garbage collection. It is therefore not worthwhile
+   to untrack eligible tuples at creation time.
+
+   Instead, all tuples except the empty tuple are tracked when created.
+   During garbage collection it is determined whether any surviving tuples
+   can be untracked. A tuple can be untracked if all of its contents are
+   already not tracked. Tuples are examined for untracking in all garbage
+   collection cycles. It may take more than one cycle to untrack a tuple.
+
+   Dictionaries containing only immutable objects also do not need to be
+   tracked. Dictionaries are untracked when created. If a tracked item is
+   inserted into a dictionary (either as a key or value), the dictionary
+   becomes tracked. During a full garbage collection (all generations),
+   the collector will untrack any dictionaries whose contents are not
+   tracked.
+
+   The module provides the python function is_tracked(obj), which returns
+   the CURRENT tracking status of the object. Subsequent garbage
+   collections may change the tracking status of the object.
+
+   Untracking of certain containers was introduced in issue #4688, and
+   the algorithm was refined in response to issue #14775.

+ * Allocation strategy abstract:
+ *
+ * For small requests, the allocator sub-allocates <Big> blocks of memory.
+ * Requests greater than SMALL_REQUEST_THRESHOLD bytes are routed to the
+ * system's allocator.
+ *
+ * Small requests are grouped in size classes spaced 8 bytes apart, due
+ * to the required valid alignment of the returned address. Requests of
+ * a particular size are serviced from memory pools of 4K (one VMM page).
+ * Pools are fragmented on demand and contain free lists of blocks of one
+ * particular size class. In other words, there is a fixed-size allocator
+ * for each size class. Free pools are shared by the different allocators
+ * thus minimizing the space reserved for a particular size class.
+ *
+ * This allocation strategy is a variant of what is known as "simple
+ * segregated storage based on array of free lists". The main drawback of
+ * simple segregated storage is that we might end up with lot of reserved
+ * memory for the different free lists, which degenerate in time. To avoid
+ * this, we partition each free list in pools and we share dynamically the
+ * reserved space between all free lists. This technique is quite efficient
+ * for memory intensive programs which allocate mainly small-sized blocks.
+ *
+ * For small requests we have the following table:
+ *
+ * Request in bytes     Size of allocated block      Size class idx
+ * ----------------------------------------------------------------

+ * Pool table -- headed, circular, doubly-linked lists of partially used pools.
+
+This is involved.  For an index i, usedpools[i+i] is the header for a list of
+all partially used pools holding small blocks with "size class idx" i. So
+usedpools[0] corresponds to blocks of size 8, usedpools[2] to blocks of size
+16, and so on:  index 2*i <-> blocks of size (i+1)<<ALIGNMENT_SHIFT.
+
+Pools are carved off an arena's highwater mark (an arena_object's pool_address
+member) as needed.  Once carved off, a pool is in one of three states forever
+after:
+
+used == partially used, neither empty nor full
+    At least one block in the pool is currently allocated, and at least one
+    block in the pool is not currently allocated (note this implies a pool
+    has room for at least two blocks).
+    This is a pool's initial state, as a pool is created only when malloc
+    needs space.
+    The pool holds blocks of a fixed size, and is in the circular list headed
+    at usedpools[i] (see above).  It's linked to the other used pools of the
+    same size class via the pool_header's nextpool and prevpool members.
+    If all but one block is currently allocated, a malloc can cause a
+    transition to the full state.  If all but one block is not currently
+    allocated, a free can cause a transition to the empty state.
+
+full == all the pool's blocks are currently allocated
+    On transition to full, a pool is unlinked from its usedpools[] list.
+    It's not linked to from anything then anymore, and its nextpool and
+    prevpool members are meaningless until it transitions back to used.
+    A free of a block in a full pool puts the pool back in the used state.
+    Then it's linked in at the front of the appropriate usedpools[] list, so
+    that the next allocation for its size class will reuse the freed block.
+
+empty == all the pool's blocks are currently available for allocation
+    On transition to empty, a pool is unlinked from its usedpools[] list,
+    and linked to the front of its arena_object's singly-linked freepools list,
+    via its nextpool member.  The prevpool member has no meaning in this case.
+    Empty pools have no inherent size class:  the next time a malloc finds
+    an empty list in usedpools[], it takes the first pool off of freepools.
+    If the size class needed happens to be the same as the size class the pool
+    last had, some pool initialization can be skipped.
+
+
+Block Management
+
+Blocks within pools are again carved out as needed.  pool->freeblock points to
+the start of a singly-linked list of free blocks within the pool.  When a
+block is freed, it's inserted at the front of its pool's freeblock list.  Note
+that the available blocks in a pool are *not* linked all together when a pool
+is initialized.  Instead only "the first two" (lowest addresses) blocks are
+set up, returning the first such block, and setting pool->freeblock to a
+one-block list holding the second such block.  This is consistent with that
+pymalloc strives at all levels (arena, pool, and block) never to touch a piece
+of memory until it's actually needed.
+
+So long as a pool is in the used state, we're certain there *is* a block
+available for allocating, and pool->freeblock is not NULL.  If pool->freeblock
+points to the end of the free list before we've carved the entire pool into
+blocks, that means we simply haven't yet gotten to one of the higher-address
+blocks.  The offset from the pool_header to the start of "the next" virgin
+block is stored in the pool_header nextoffset member, and the largest value
+of nextoffset that makes sense is stored in the maxnextoffset member when a
+pool is initialized.  All the blocks in a pool have been passed out at least
+once when and only when nextoffset > maxnextoffset.
+
+
+Major obscurity:  While the usedpools vector is declared to have poolp
+entries, it doesn't really.  It really contains two pointers per (conceptual)
+poolp entry, the nextpool and prevpool members of a pool_header.  The
+excruciating initialization code below fools C so that
+
+    usedpool[i+i]
+
+"acts like" a genuine poolp, but only so long as you only reference its
+nextpool and prevpool members.  The "- 2*sizeof(pymem_block *)" gibberish is
+compensating for that a pool_header's nextpool and prevpool members
+immediately follow a pool_header's first two members:
+
+    union { pymem_block *_padding;
+            uint count; } ref;
+    pymem_block *freeblock;
+
+each of which consume sizeof(pymem_block *) bytes.  So what usedpools[i+i] really
+contains is a fudged-up pointer p such that *if* C believes it's a poolp
+pointer, then p->nextpool and p->prevpool are both p (meaning that the headed
+circular list is empty).
+
+It's unclear why the usedpools setup is so convoluted.  It could be to
+minimize the amount of cache required to hold this heavily-referenced table
+(which only *needs* the two interpool pointer members of a pool_header). OTOH,
+referencing code has to remember to "double the index" and doing so isn't
+free, usedpools[0] isn't a strictly legal pointer, and we're crucially relying
+on that C doesn't insert any padding anywhere in a pool_header at or before
+the prevpool member.

+Arena management.
+
+`arenas` is a vector of arena_objects.  It contains maxarenas entries, some of
+which may not be currently used (== they're arena_objects that aren't
+currently associated with an allocated arena).  Note that arenas proper are
+separately malloc'ed.
+
+Prior to Python 2.5, arenas were never free()'ed.  Starting with Python 2.5,
+we do try to free() arenas, and use some mild heuristic strategies to increase
+the likelihood that arenas eventually can be freed.
+
+unused_arena_objects
+
+    This is a singly-linked list of the arena_objects that are currently not
+    being used (no arena is associated with them).  Objects are taken off the
+    head of the list in new_arena(), and are pushed on the head of the list in
+    PyObject_Free() when the arena is empty.  Key invariant:  an arena_object
+    is on this list if and only if its .address member is 0.
+
+usable_arenas
+
+    This is a doubly-linked list of the arena_objects associated with arenas
+    that have pools available.  These pools are either waiting to be reused,
+    or have not been used before.  The list is sorted to have the most-
+    allocated arenas first (ascending order based on the nfreepools member).
+    This means that the next allocation will come from a heavily used arena,
+    which gives the nearly empty arenas a chance to be returned to the system.
+    In my unscientific tests this dramatically improved the number of arenas
+    that could be freed.
+
+Note that an arena_object associated with an arena all of whose pools are
+currently in use isn't on either list.
+
+Changed in Python 3.8:  keeping usable_arenas sorted by number of free pools
+used to be done by one-at-a-time linear search when an arena's number of
+free pools changed.  That could, overall, consume time quadratic in the
+number of arenas.  That didn't really matter when there were only a few
+hundred arenas (typical!), but could be a timing disaster when there were
+hundreds of thousands.  See bpo-37029.
+
+Now we have a vector of "search fingers" to eliminate the need to search:
+nfp2lasta[nfp] returns the last ("rightmost") arena in usable_arenas
+with nfp free pools.  This is NULL if and only if there is no arena with
+nfp free pools in usable_arenas.

+//--- HAVE_PY_SET_53BIT_PRECISION macro ------------------------------------
+//
+// The functions _Py_dg_strtod() and _Py_dg_dtoa() in Python/dtoa.c (which are
+// required to support the short float repr introduced in Python 3.1) require
+// that the floating-point unit that's being used for arithmetic operations on
+// C doubles is set to use 53-bit precision.  It also requires that the FPU
+// rounding mode is round-half-to-even, but that's less often an issue.
+//
+// If your FPU isn't already set to 53-bit precision/round-half-to-even, and
+// you want to make use of _Py_dg_strtod() and _Py_dg_dtoa(), then you should:
+//
+//     #define HAVE_PY_SET_53BIT_PRECISION 1
+//
+// and also give appropriate definitions for the following three macros:
+//
+// * _Py_SET_53BIT_PRECISION_HEADER: any variable declarations needed to
+//   use the two macros below.
+// * _Py_SET_53BIT_PRECISION_START: store original FPU settings, and
+//   set FPU to 53-bit precision/round-half-to-even
+// * _Py_SET_53BIT_PRECISION_END: restore original FPU settings
+//
+// The macros are designed to be used within a single C function: see
+// Python/pystrtod.c for an example of their use.

+/*
+Objects are structures allocated on the heap.  Special rules apply to
+the use of objects to ensure they are properly garbage-collected.
+Objects are never allocated statically or on the stack; they must be
+accessed through special macros and functions only.  (Type objects are
+exceptions to the first rule; the standard types are represented by
+statically initialized type objects, although work on type/class unification
+for Python 2.2 made it possible to have heap-allocated type objects too).
+
+An object has a 'reference count' that is increased or decreased when a
+pointer to the object is copied or deleted; when the reference count
+reaches zero there are no references to the object left and it can be
+removed from the heap.
+
+An object has a 'type' that determines what it represents and what kind
+of data it contains.  An object's type is fixed when it is created.
+Types themselves are represented as objects; an object contains a
+pointer to the corresponding type object.  The type itself has a type
+pointer pointing to the object representing the type 'type', which
+contains a pointer to itself!.
+
+Objects do not float around in memory; once allocated an object keeps
+the same size and address.  Objects that must hold variable-size data
+can contain pointers to variable-size parts of the object.  Not all
+objects of the same type have the same size; but the size cannot change
+after allocation.  (These restrictions are made so a reference to an
+object can be simply a pointer -- moving an object would require
+updating all the pointers, and changing an object's size would require
+moving it if there was another object right next to it.)
+
+Objects are always accessed through pointers of the type 'PyObject *'.
+The type 'PyObject' is a structure that only contains the reference count
+and the type pointer.  The actual memory allocated for an object
+contains other data that can only be accessed after casting the pointer
+to a pointer to a longer structure type.  This longer type must start
+with the reference count and type fields; the macro PyObject_HEAD should be
+used for this (to accommodate for future changes).  The implementation
+of a particular object type can cast the object pointer to the proper
+type and back.
+
+A standard interface exists for objects that contain an array of items
+whose size is determined when the object is allocated.

+ * Note that "the obvious" code can be deadly:
+ *
+ *     Py_XDECREF(op);
+ *     op = NULL;
+ *
+ * Typically, `op` is something like self->containee, and `self` is done
+ * using its `containee` member.  In the code sequence above, suppose
+ * `containee` is non-NULL with a refcount of 1.  Its refcount falls to
+ * 0 on the first line, which can trigger an arbitrary amount of code,
+ * possibly including finalizers (like __del__ methods or weakref callbacks)
+ * coded in Python, which in turn can release the GIL and allow other threads
+ * to run, etc.  Such code may even invoke methods of `self` again, or cause
+ * cyclic gc to trigger, but-- oops! --self->containee still points to the
+ * object being torn down, and it may be in an insane state while being torn
+ * down.  This has in fact been a rich historic source of miserable (rare &
+ * hard-to-diagnose) segfaulting (and other) bugs.
+ *
+ * The safe way is:
+ *
+ *      Py_CLEAR(op);
+ *
+ * That arranges to set `op` to NULL _before_ decref'ing, so that any code
+ * triggered as a side-effect of `op` getting torn down no longer believes
+ * `op` points to a valid object.
+ *
+ * There are cases where it's safe to use the naive code, but they're brittle.
+ * For example, if `op` points to a Python integer, you know that destroying
+ * one of those can't cause problems -- but in part that relies on that
+ * Python integers aren't currently weakly referencable.  Best practice is
+ * to use Py_CLEAR() even if you can't think of a reason for why you need to.
+ *
+ * gh-98724: Use a temporary variable to only evaluate the macro argument once,
+ * to avoid the duplication of side effects if the argument has side effects.
+ *
+ * gh-99701: If the PyObject* type is used with casting arguments to PyObject*,
+ * the code can be miscompiled with strict aliasing because of type punning.
+ * With strict aliasing, a compiler considers that two pointers of different
+ * types cannot read or write the same memory which enables optimization
+ * opportunities.
+ *
+ * If available, use _Py_TYPEOF() to use the 'op' type for temporary variables,
+ * and so avoid type punning. Otherwise, use memcpy() which causes type erasure

+More conventions
+================
+
+Argument Checking
+-----------------
+
+Functions that take objects as arguments normally don't check for nil
+arguments, but they do check the type of the argument, and return an
+error if the function doesn't apply to the type.
+
+Failure Modes
+-------------
+
+Functions may fail for a variety of reasons, including running out of
+memory.  This is communicated to the caller in two ways: an error string
+is set (see errors.h), and the function result differs: functions that
+normally return a pointer return NULL for failure, functions returning
+an integer return -1 (which could be a legal return value too!), and
+other functions return 0 for success and -1 for failure.
+Callers should always check for errors before using the result.  If
+an error was set, the caller must either explicitly clear it, or pass
+the error on to its caller.
+
+Reference Counts
+----------------
+
+It takes a while to get used to the proper usage of reference counts.
+
+Functions that create an object set the reference count to 1; such new
+objects must be stored somewhere or destroyed again with Py_DECREF().
+Some functions that 'store' objects, such as PyTuple_SetItem() and
+PyList_SetItem(),
+don't increment the reference count of the object, since the most
+frequent use is to store a fresh object.  Functions that 'retrieve'
+objects, such as PyTuple_GetItem() and PyDict_GetItemString(), also
+don't increment
+the reference count, since most frequently the object is only looked at
+quickly.  Thus, to retrieve an object and store it again, the caller
+must call Py_INCREF() explicitly.
+
+NOTE: functions that 'consume' a reference count, like
+PyList_SetItem(), consume the reference even if the object wasn't
+successfully stored, to simplify error handling.
+
+It seems attractive to make other functions that take an object as
+argument consume a reference count; however, this may quickly get
+confusing (even the current practice is already confusing).  Consider
+it carefully, it may save lots of calls to Py_INCREF() and Py_DECREF() at
+times.

+Functions and macros for modules that implement new object types.
+
+ - PyObject_New(type, typeobj) allocates memory for a new object of the given
+   type, and initializes part of it.  'type' must be the C structure type used
+   to represent the object, and 'typeobj' the address of the corresponding
+   type object.  Reference count and type pointer are filled in; the rest of
+   the bytes of the object are *undefined*!  The resulting expression type is
+   'type *'.  The size of the object is determined by the tp_basicsize field
+   of the type object.
+
+ - PyObject_NewVar(type, typeobj, n) is similar but allocates a variable-size
+   object with room for n items.  In addition to the refcount and type pointer
+   fields, this also fills in the ob_size field.
+
+ - PyObject_Free(op) releases the memory allocated for an object.  It does not
+   run a destructor -- it only frees the memory.  PyObject_Free is identical.
+
+ - PyObject_Init(op, typeobj) and PyObject_InitVar(op, typeobj, n) don't
+   allocate memory.  Instead of a 'type' parameter, they take a pointer to a
+   new object (allocated by an arbitrary allocator), and initialize its object
+   header fields.
+
+Note that objects created with PyObject_{New, NewVar} are allocated using the
+specialized Python allocator (implemented in obmalloc.c), if WITH_PYMALLOC is
+enabled.  In addition, a special debugging allocator is used if Py_DEBUG
+macro is also defined.
+
+In case a specific form of memory management is needed (for example, if you
+must use the platform malloc heap(s), or shared memory, or C++ local storage or
+operator new), you must first allocate the object with your custom allocator,
+then pass its pointer to PyObject_{Init, InitVar} for filling in its Python-
+specific fields:  reference count, type pointer, possibly others.  You should
+be aware that Python has no control over these objects because they don't
+cooperate with the Python memory manager.  Such objects may not be eligible
+for automatic garbage collection and you have to make sure that they are
+released accordingly whenever their destructor gets called (cf. the specific
+form of memory management you're using).
+
+Unless you have specific memory management requirements, use
+PyObject_{New, NewVar, Del}.
