bpo-35053: Enhance tracemalloc to trace free lists (GH-10063)
tracemalloc now tries to update the traceback when an object is reused from a "free list" (optimization for faster object creation, used by the builtin list type for example). Changes: * Add _PyTraceMalloc_NewReference() function which tries to update the Python traceback of a Python object. * _Py_NewReference() now calls _PyTraceMalloc_NewReference(). * Add an unit test.
