I think the overall goal should be to get rid of 
http://github.com/gregorycollins/event/blob/master/src/System/Event/EPoll.hsc, 
as it's in the core.
Any non-blocking call to select should be save to replace by epoll, as 
the semantics are the same. As epoll is considerably more fine grained 
than non-blocking select, the architecture must support a run loop which 
effectively retrieves events faster than non-blocking select would do. 
Otherwise the effort would be futile.
