Could this mean that we might want _both_ ?

1) a minimal guaranteed working set for small processes, so root
   can login and large hogs don't penalize good guys
   (simpler than the working set idea, should work just as good)

2) load control through process suspension when the load gets
   too high to handle, this is also good to let the hogs (which
   would thrash with the working set idea) make some progress
   in turns
