I had posted a suggestion several month ago recommending that we implement
processing locking on programs like findutils which may run for extended
periods of time. We often use the ``shlock'' program from the inn news
software to handle this locking in shell scripts.
Using lock files like %{l_prefix}/var/$package/run/hourly.lock with shlock
is reasonably safe given the minimum time interval is fifteen minutes for
quarterly cron jobs.
