I don't see why you want to use EventFD and not Condition.wait/signal. In 
particular, Condition.broadcast does exactly the last thing you mention.

Now, I don't understand why you asked for related modules and and the end 
discard all of them and post your own implementation. Your issue is not that 
complex you could have done that in the first place...
