Well, "the memory allocator" doesn't exist -- there's no choke point for
allocations, outside of the platform C malloc.  If the latter has
instrumentation, then it can be asked.  The Python object allocator knows
how many "arenas" it has in hand, so that part is easy, but not everything
goes thru the Python object allocator.  Even so, the Python object allocator
has no idea how much memory is actually consumed by the platform C malloc
when it asks the latter for "an arena".  Bottom line:  all memory ultimately
comes from C malloc, and only C malloc knows what C malloc really does.
