  Modified files:
    sys/kern             sched_ule.c 
  Log:
  Give a more reasonable CPU time to the threads which are using scheduler
  activation (i.e., applications are using libpthread).  This is because
  SCHED_ULE sometimes puts P_SA processes into ksq_next unnecessarily.
  Which doesn't give fair amount of CPU time to processes which are
  using scheduler-activation-based threads when other (semi-)CPU-intensive,
  non-P_SA processes are running.
  
  Further work will no doubt be done by jeffr at a later date.
