Yep, I'am thinking along this lines - one thread is getting the state update
for multiple events and spreading it to waiting worker threads through
semaphore or else
I assume there is no protection of multiple threads waking up from
single event(one of the
epoll original problems which was fixed with a new flag).

The worker threads are free to submit new job requests directly into
the SQE though(without a proxy job list).
