+/* Interface for threads.
+
+   A module that plans to do a blocking system call (or something else
+   that lasts a long time and doesn't touch Python data) can allow other
+   threads to run as follows:
+
+    ...preparations here...
+    Py_BEGIN_ALLOW_THREADS
+    ...blocking system call here...
+    Py_END_ALLOW_THREADS
+    ...interpret result here...
+
+   The Py_BEGIN_ALLOW_THREADS/Py_END_ALLOW_THREADS pair expands to a
+   {}-surrounded block.
+   To leave the block in the middle (e.g., with return), you must insert
+   a line containing Py_BLOCK_THREADS before the return, e.g.
+
+    if (...premature_exit...) {
+        Py_BLOCK_THREADS
+        PyErr_SetFromErrno(PyExc_IOError);
+        return NULL;
+    }
+
+   An alternative is:
+
+    Py_BLOCK_THREADS
+    if (...premature_exit...) {
+        PyErr_SetFromErrno(PyExc_IOError);
+        return NULL;
+    }
+    Py_UNBLOCK_THREADS
+
+   For convenience, that the value of 'errno' is restored across
+   Py_END_ALLOW_THREADS and Py_BLOCK_THREADS.
+
+   WARNING: NEVER NEST CALLS TO Py_BEGIN_ALLOW_THREADS AND
+   Py_END_ALLOW_THREADS!!!
+
+   The function PyEval_InitThreads() should be called only from
+   initthread() in "threadmodule.c".
+
+   Note that not yet all candidates have been converted to use this
+   mechanism!
