-Always use PyMem_RawMalloc() and PyMem_RawFree() directly in this file.  A
-number of these functions are advertised as safe to call when the GIL isn't
-held, and in a debug build Python redirects (e.g.) PyMem_NEW (etc) to Python's
-debugging obmalloc functions.  Those aren't thread-safe (they rely on the GIL
-to avoid the expense of doing their own locking).
