Long Lived imapd processes

Whenever we reboot, it takes only about 15-20 minutes to get
to the same number of imapd processes as before the reboot.
I've never checked, but I suspect the clients just reconnect.
That requires re-authenticating, which uses a lot more resources
than responding to a NOOP every few minutes.  (Note - we are
using an ancient Cyrus derivative, not Cyrus itself).
