EPOLL_CTL_POKE may be used to force an item into the epoll
ready list.  Instead of disabling an item asynchronously
via EPOLL_CTL_DISABLE, this forces the threads calling
epoll_wait() to handle the item in its normal loop.

That was my initial suggestion as well - see

Thanks, missed that the first time around.  Perhaps TRIGGER is a
better name than POKE :x

I'm hoping Paton has a chance to look at my implementation and
comment on it.
