[ZODB-Dev] BTree reference counting assertion bug

[Toby Dickenson]

I have a reproducible assertion from BTreeTemplate.c, the "Invalid
firstbucket pointer" in _BTree_Clear.

This assertion is about the number of reference counts. I wonder
whether this assetion is out by one when using my new cache (which
uses weak references for this type of object)?

Everything seems to work happily when I remove the assertion.

Any thoughts?
