tp_free is NULL or PyObject_Del at the end. Because it's a base type it must call tp_free in its dealloc function, and because it's gc'able it must not call PyObject_Del. inherit_slots(): Don't inherit tp_free unless the type and its base agree about whether they're gc'able. If the type is gc'able and the base is not, and the base uses the default PyObject_Del for its tp_free, give the type PyObject_GC_Del for its tp_free (the appropriate default for a gc'able type). cPickle.c: The Pickler and Unpickler types claim to be base classes and gc'able, but their dealloc functions didn't call tp_free. Repaired that. Also call PyType_Ready() on these typeobjects, so that the correct (PyObject_GC_Del) default memory-freeing function gets plugged into these types' tp_free slots.
