By the way, you probably want to also delete func_globals and 
func_defaults, as there are security ramifications to those 
attributes as well.  Probably not so much for func_dict/__dict__ though.

And of course, for Python<=2.4 you can just use the __call__ 
attribute and not bother with deleting anything but __subclasses__.
