To be run on the client, this script looks for chroot directories that have not been

used in 20 minutes, as well as directories listed as 'in use' that have not been touched
in 24 hours (corresponding to port builds that have timed out or shut down uncleanly)
and prunes them to reclaim space.  This is intended to be run as a cron job.
