  Modified files:
    sys/kern             sched_ule.c 
  Log:
   - Improve grammar.  s/it's/its/.
   - Improve load long-term load balancer by always IPIing exactly once.
     Previously the delay after rebalancing could cause problems with
     uneven workloads.
   - Allow nice to have a linear effect on the interactivity score.  This
     allows negatively niced programs to stay interactive longer.  It may be
     useful with very expensive Xorg servers under high loads.  In general
     it should not be necessary to alter the nice level to improve interactive
     response.  We may also want to consider never allowing positively niced
     processes to become interactive at all.
   - Initialize ccpu to 0 rather than 0.0.  The decimal point was leftover
     from when the code was copied from 4bsd.  ccpu is 0 in ULE because ULE
     only exports weighted cpu values.
