This doesn't fail in 2.5/master, because it unlocks the mailbox entirely between cmdloop cycles.

The SELECTed processes will freeze when they hit one of these folders, waiting on the lock that's being held by the process doing the rename. If they get the lock and it's still in the RENAME state, then obviously the renaming process crashed, so it will perform a rollback of the rename. Obviously, if they get the lock and the folder has changed to type DELETED, then they'll do the normal thing on a deleted folder. Cheers, Bron. -- Bron Gondwana br...@fastmail.fm
