[Zope-Coders] BTrees memory leak?

Really?  Couldn't a circular reference involving an object whose type
doesn't support garbage collection create a leak?  AFAIK
ExtensionClass objects don't support GC.

Maybe the test suite creates circular references but other apps are
more careful to avoid those (because in general ExtensionClass leaks
any cycles you create, and Zope programmers know that)?
