Actually, reconstruct doesn't do anything about it - it doesn't kill off the
connections.  The procedure to recover is just to disconnect all clients
(potentially by restarting the server) and then visit all mailboxes
(cyr_expire will do that - as will reconstruct.  I would recommend
reconstruct -s to reduce the IO hit if you go that path)
