I think that's all way too much trouble and has potential problems with
leaking file descriptors. Dovecot 2.0 framework will have separate
logging processes, and those could possibly live even after master has
died until all log clients have died (I think it already works that
way..)

Now that I think of it, that won't work. The imap/pop3 processes kill
themselves when they notice that the stderr pipe gets closed, so I can't
think of a way for master to notify the imap/pop3 processes on-the-fly
that they shouldn't die. Guess I'll add a setting instead.
