NEBERROR_CALLBACKCANCEL is used as a one-time measure to cancel
checks, while NEBERROR_CALLBACKOVERRIDE is used to cancel them
without rescheduling them. I'm not sure if we want to muddy the
distinctions by having them mean the same for things that aren't
re-scheduled automagically.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
