I'm about to cut the beta this morning, and I don't have spare cycles
to review the feature.  We'll get the final release out in no more
than two weeks and try to move on to a ZODB3 3.2 release not to long
after that.  Barry's working on a new bsddb3Storage implementation,
and I'd like to see ZEO cache validation sped up.  So there are other
reasons to expect that the 3.2 release will come fairly soon after the
3.1 release.
