Fastmail runs our own "imappool" which is a funky daemon capable
of passing FDs around between processes.  I don't know how it works
precisely, but it uses Socket::Pool which had a sourceforge project
and doesn't appear to any more.  My guess is that I'd rather not
look at the code for fear of going totally insane.

But yeah, connection caching is nice.  Even just the fork overhead
on the backend servers is something we can do without if it's
avoidable.
