cpython-lru_cache-weakref: Python/structmember.c annotate

annotate Python/structmember.c @ 31058:bf7df48012cb 2.3

Py_Finalize(): disabled the second call of cyclic gc, and added extensive comments about why both calls to cyclic gc here can cause problems. Already fixed on the trunk. Since the calls were introduced in 2.3, that's the end of it.
