In the only case I've looked into deeply, the imap processes all seem
to be sitting in this state, idle:

#0  0x18290f0b in kevent () from /lib/libc.so.6
#1  0x080c97fc in io_loop_handler_run (ioloop=0x80f0160) at ioloop-kqueue.c:128
#2  0x080c8e59 in io_loop_run (ioloop=0x80f0160) at ioloop.c:326
#3  0x08065ed0 in main (argc=1, argv=0xbfbfea1c, envp=0xbfbfea24) at main.c:293

I don't see how that could be holding anything up.  It feels a bit odd
that clients have 30+ separate imap processes open, all sitting in the
io loop.

I'll get back to you if I find any more useful information.

Thanks!
