1) We don't have a pthreads implementation with kernel assists yet, so
   that will suck for you.
2) The right solution is really the kqueue API. Unfortunately, the
   code is currently on a branch, not in the mainline, but it should
   be out and available "soon".
3) Meanwhile, I'd use select until kqueue is available.
