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

annotate Python/ceval.c @ 1207:b564bd4e57e1 legacy-trunk

* ceval.c: ifdef out the last argument passing compat hack. * Fixed memory leaks in socket, select and sv modules: mkvalue("O", v) does INCREF(v) so if v is brand new it should be XDECREF'd
