The tp_alloc slot function returns a valid object except for user 
defined fields, which are zeroed memory. PyType_GenericNew() makes 
the call without doing anything else. So this should be what is 
wanted. The problem with Pyrex are C methods. So what is needed is 
some kind of extension type specific allocation operation that calls 
tp_alloc and sets the vtable field, if any.
