>    Affects Versions: 2.0.0a

> Currently threads waiting for IO which have events posted to them (e.g. newly accepted sockets for
> traffic servers using an accept thread) do not get knocked off the poll wait to process the new event.
> This can be done with pipe's linux's fdevent and more generally with libev ev_async.
> This improvement would optionally enable this functionality.
