 In some cases there are some problems with wp_schedule_event. It schedule
 the event, if we use wp_next_scheduled, it gives a timestamp, but using WP
 Crontrol, it doesn't appear there.
 Below some code to reproduce it.
 If you click on the button, it will schedule 500 events. Wait a bit, that
 100 or so are processed (look at the logs or use WP Control to check).
 Then click again. The logs show that they should have been schedules,
 there is a timestamp and the transient is created. But it's not really
 scheduled, it doesn't appear with WP Control, and the transient is not
 deleted (for the 2nd round)
