They don't have to do anything extra now -- registering with gc is
sufficient in current CVS.  It's also a fine fit:  if they're fat containers
for which the trashcan is appropriate, they can also be involved in cycles.

Note too that people can get back more memory than gc consumes by declaring
new-style classes to use __slots__.  That's a new memory-optimization
gimmick, and an effective one.
