you misread the crontab. cron is ALWAYS running. when a scheduled job comes
up the items in crontab first check if anacron exists. if it does, cron
assumes anacron will eventually take care of it and nothing happens.
Remember, cron is still the thing that handles schedules, it just passes the
real work on to anacron.
