Comment:
I would like some comments on this patch before I apply it.  First,
there must be a matching PyObject_GC_Fini() for every
PyObject_GC_Init().  Second of all, between the Init and Fini calls, all
pointers in the object struct followed by tp_recurse must be valid.  GC
can be triggered at wierd times.

The problem with classobject.c was that if PyDict_New() failed,
PyObject_DEL() was used to free the instance (which does not call
PyObject_GC_Fini()).

The problem with cPickle.c was that if PyDict_New() failed, Py_DECREF()
was called to free the instance.  Py_DECREF() will call
instance_dealloc() which calls PyObject_GC_Fini().
