From what I can tell, I think the error may be that you're ending the
event early, but whatever variable holds the pointer to the event struct
isn't getting set to NULL. That is, something like this occurs:

  if (GET_SOMEEVENT(ch) != NULL) {

Or, rather than cancelling the event, you just let it default to not
scheduling the event again in your eventfunc but GET_SOMEEVENT(ch) still
isn't getting NULLed.

BTW- it's been a couple months since I looked at the events, so I might be
on crack. :)
