I like Marc's suggestion. Here is my proposal:
Allow classes to have a new method, __cleanup__ or whatever you
want to call it. When tp_clear is called for an instance, it
checks for this method. If it exists, call it, otherwise delete
the container objects from the instance's dictionary. When
collecting cycles, call tp_clear for instances first.
Its simple and allows the programmer to cleanly break cycles if
they insist on creating them and using __del__ methods.
