No, it's a real problem I had in my current project. You can't delete
complex data structures just deleting component objects in random order.

I am just suggesting a way to improve the mark sweet collector you
talked about. Calling the __del__ method could be the default behavior
for it, but a new method hook could add better functionality...
BTW, usual __del__ methods free resources like sockets, files, windows,
etc. but they don't break circular references so calling __del__ will
not free any object at all.
