Tried it, doesn't work. The problem is that this always goes through the actual type of the object, ignoring the type hierarchy completely, which kills the tp_dealloc() call chain and runs into an infinite loop starting from the second inheritance level (or a crash because of multiple DECREF calls on the same fields).
