I agree. Thank you for injecting some intelligence into this

I have a new patch in the works. Just to wet your appetite:
* It is portable. It should run anywhere Python runs.
* It does not require rewriting or recompiling existing
* It has very low overhead.
The bad news is that:
* It only finds cycles that involve lists, tuples,
dictionaries, instances and classes and that have a least
one dictionary in them.
* __del__ methods sometimes may not be called for instances
involved in cycles.
* It requires some extra memory when doing the collection.
I still need to clean up and test the patch some more but things
are looking good. It currently is not thread safe but should be
possible to make so. If anyone is interested in helping out or
testing it, a prelimiary patch is at:
Comments are definitely appreciated.
