[issue19831] tracemalloc: stop the module later

[STINNER Victor]

New submission from STINNER Victor:

tracemalloc cannot be used in object destructors because the module is stopped early at Python shutdown.

I would like to use tracemalloc.get_object_traceback() in object destructors to retrieve where an object was allocated.

Attached patch replaces the atexit handler with a builtin _PyTraceMalloc_Fini() function to stop tracemalloc much later. It does also simplify the C code of _tracemalloc.c.
