Subject: [PATCH] This is a force commit for revision 1.90 to explain further:
 Removes a surplus kse_wakeup_multi call when there is no thread can run. Also
 reduce time window that an IDLE kse wakes and sleeps again because it can not
 get scheduler lock after wakeup, the change is small and not perfect, futher
 refining it is possible but may not worth to do, it is unknown whether we can
 gain performance benifit by refining it.
