[Zope] Refcounts, ZODB Cache and memory leaks?

Hi, I'm trying to track down some memory leaks using LeakFinder. I get some custom objects with refcounts that keep going up on use. When I patch them using leakfinder I get no results which should be correct as they should be loaded from the ZODB rather than created. The problem is, why won't they go away after GC or clearing the ZODB cache? If anyone has experience with finding these kind of rouge references I'd really appreciate any tips.
