The standard reference counting that Python uses cannot detect
reference cycles.  You could compile a new interpreter with
Py_TRACE_REFS defined.  The interpreter can then show you which
objects are still alive when it is shutting down.  You could also
grab my garbage collection patch from:

    http://www.enme.ucalgary.ca/~nascheme/python/gc.html

It allows reference cycles to be debugged quite easily.
