There's only one that I'd really want to push for inclusion soon, and that's:
http://cyrus.brong.fastmail.fm/cyrus-sync-connectonce-2.3.7.diff

it's not absolutely the shortest diff, but it should only take 10-15 minutes
to review since it does very little.  This makes replication master startup a
lot less painful if your replica is down.

The other diff that's very small and we quite like is:
http://cyrus.brong.fastmail.fm/cyrus-reusetimeout-2.3.6.diff

Which reduces the IO hit on an IMAP server if all its connections get
dropped at once due to network issues by spreading out the disconnect
timeouts - but that's less of a priority.  The first one was necessary
to make replication even usable in our environment (master IMAP servers
hanging at (re)start sucks).
