cron question / process queue

[Bruce Dawson]

You can also use dotlockfile, lockfile, or dotlock to create a lock file
for each task that is running. Then have the 'daily' script kick off the
right process for whichever lockfile is not there.

Of course, the task has to remove the lock file when its done.
