Specifically sections 3 and 4, on lsof and strace, the latter of which
should be informative re: what the threads are doing when they're not
responding to a shutdown, provided you can catch one "in the act".

Does this happen -every- time you issue a shutdown, or only after the
cluster has been running for awhile?

This is otherwise stock mongrel behaviour; it's just trying to comply with a
shutdown request, and will forcibly kill threads that are unresponsive.
