We have  prefork=0  set on all Cyrus services for many years now.

We have a handful with "prefork=1 maxchild=1" (one for each service
type) listening on separate ports that can be connected for debugging.
The advantage here being that the process is already waiting for you to
connect a debugger before using it.
But yeah, otherwise we have prefork=0 at FastMail too. Fork is pretty
fast compared to everything else in an IMAP session.
