There lave been various BTree fixes lounging in the HEAD since Jan 2003 which I'd like to get into a release, basically because we have seen one of the bugs causing segfaults in production - this is the culprit: http://cvs.zope.org/Zope/lib/python/BTrees/BTreeItemsTemplate.c.diff?r1=1.17&r2=1.18 a) Any reason why I shouldn't merge it into the 2.6 branch? b) Any chance of a 2.6.2b3?
