By that, I meant that if you deleted a non-empty Container, its Items
would still carry a reference to it.  You pretty much answered this
question in your response to my question about the potential for
recursive issues.

Sounds like I should be sure to write a __del__ method for Container
that ensures things work correctly.

Thanks for your comments,
