This new approach handles things as follows:
1. Fences won't be attached to events anymore, applications only wait on
the cv attached to the event.
2. Only the queue is allowed to update event status for non user events.
This will eliminate all remaining status updating races between the
queue and applications waiting on events.
3. Queue minimized flushing by bundling events
4. Increase cv wait timeout as there is really no point in waking up too
often.
