After all the current events are processed in the main loop, the next pending event is marked to fire an interrupt to start the cycle anew. When the event is marked, we check the timestamp again to make sure that we are always caught up with the GPU. If the timestamp for the next event happens to be retired when we get to this point, we silently leave the function. If there are no other subsequent events or waittimestamp requests, then it is possible that another interrupt might never be fired for that context and then the event gets missed. Return a 1 in this case all the way back up the stack and make the event code keep processing events until we are positive that none are past.
