Hm, after a full working day, it seems that we still had the problem, so I
reverted to rc1 once more.  The problem seems to appear only after some
period of time.  

Now I'm suspecting it is a totally different problem: the default polling
method changed in rc2.  I think I was having the "stale imap processes"
problem, mentioned elsewhere on this list, and that was causing timeouts
for clients connecting after the process limit was hit.  I'll recompile
dovecot 1.0rc6 with --with-ioloop=kqueue, as suggested elsewhere on this
list, and try again.  I should have mentioned I'm using NetBSD...
