kqueue is preferred on *BSD, since it's able to aggregate multiple filter 
matches into one event if they happen to occur in a close time frame. This 
reduces copyout from kernel to userland. It also used to be true that poll is 
a busywait, but I think that has been corrected.

If you're interested, the original design document for kqueue is available 
here:
