I agree that this is 1.3.1-able. But I would caution against an overly
quick release of this code. News of BDB 4.4 support will be welcomed by
Subversion users everywhere, and we want to make sure that the hype is
backed by soundly tested code.

Would you (or anyone else) object to our running an RC cycle (maybe two
weeks) for the 1.3.1 release, during which time I can get svn.collab.net
running BDB 4.4 and subversion-1.3.1-rc1? For kicks I could even write
a cron job on that box that runs a binary which opens the repository and
then abort()s. :-)

Shucks. What a bummer.
