Killing eventing processes can cause timers in flight to be lost

It's a known limitation that if eventing process is killed externally, it may lose timers that have been dequeued but not run to completion. This is because eventing-producer does not follow a Request & Acknowledge protocol when queuing events to v8 workers. As a result, forcibly killing the eventing producer OS process will cause the timers that have been dequeued from storage but not yet fired by v8 workers to be lost.
