PyMem_DEL should not be used since it could be using a different
allocator then PyObject_New.

Why would it bomb? It doesn't do anything special as far as I can tell
except free memory. Vladimir went a bit overboard with the
pre-processor, IMHO, so its a little hard to tell for certain.

PyObject_Del() doesn't call the deallocator function.
