  Log:
  Yet more scheduler work.  Revamp the batch detection heuristic and fix a few
  things here and there.  Test the algorithm against buildworlds, mozilla,
  gnome-terminal, and pine all running at once.
  
  * Fix a bug in how I handle p_slptime.
  * Move the ++p_cptime out of usched_bsd4 and into kern_clock.c.
  * Redo the batch heuristic, boost the cost of doing a fork, and
    slowly decrement p_origcpu to compensate for long-running
    processes.
  * Use an instantanious load instead of a time-averaged load in the
    decay calculation.
  
  TODO: the SMP support will be virtually identical across all schedulers
  and should probably be abstracted out of usched_*.c.
