    sys/sys              proc.h 
    sys/kern             kern_sig.c kern_thr.c kern_thread.c 
                         subr_sleepqueue.c subr_trap.c 
  Log:
   - Add a new td flag TDF_NEEDSUSPCHK that is set whenever a thread needs
     to enter thread_suspend_check().
   - Set TDF_ASTPENDING along with TDF_NEEDSUSPCHK so we can move the
     thread_suspend_check() to ast() rather than userret().
   - Check TDF_NEEDSUSPCHK in the sleepq_catch_signals() optimization so
     that we don't miss a suspend request.  If this is set use the
     expensive signal path.
   - Set NEEDSUSPCHK when creating a new thread in thr in case the
     creating thread is due to be suspended as well but has not yet.
