I've noticed this using maildir, luckily we have an SMP server so it
doesn't affect it to much, but obviously I would like to stop it.

Doesn't happen to all users and doesn't seem to be dependent on size of
Maildir, sending SIGTERM makes it go away and then the user opens the
mailbox again and I see normal CPU usage. However 3-4 hours later it
will happen again.

Using FreeBSD 4.9 and dovecot-0.99.10.4, postfix 2.0.18 as MTA.

If theres any other info that would be useful (this is probably the most
vauge description I can manage, but its all the info I have) then let me
know and I can provide.
