Hmm, while you are on it, how is it possible to have entry==NULL for should_restart_cycle(). It is only called in advance_sched() where entry is already checked against NULL right before it, so for me, entry is always NULL at the point of calling should_restart_cycle(). Am I missing anything? Thanks.
