 wp_schedule_event() checks if the interval (hourly, daily, etc) of the
 event is valid, but it does not check if the event is already scheduled.
 A simple check of the cron array should return false if the event already
 exists.
 This will prevent crippling DB queries resulting from endless duplication
 of scheduled events
