Set socket timer to 58 instead of 60 minutes for hour-old cleaners:

         * Touch the socket and lock file at least every hour, to
         * ensure that they are not removed by overzealous /tmp-cleaning
         * tasks.  Set to 58 minutes so a cleaner never sees the
         * file as an hour old.
