A well known bug -- said to be fixed in Zope 2.8 (because there
the cyclic garbage collector can collect ExtensionClass objects
and therefore get rid of the cyclic cache/content structure).

It is also easily fixable in earlier Zope versions:

   In "ZODB.Connection.Connection._resetCache"
   add "orig_cache.clear()" before
   "self._cache = cache = PickleCache(...)".

A bug.
