Ok. I should have not mentioned the second caveat. The real point is 
that epoll is meant to reduce complexity of polling from O(n) -- where n 
is the size of pollset -- to O(1). If we use epoll to implement 
zmq_poll(), we get complexity of O(n log n) which is actually worse than 
O(n) that you get using poll or select.
