    sys/kern             kern_sig.c 
  Log:
  In kern_sigtimedwait, remove waitset bits for td_sigmask before
  sleeping, so in do_tdsignal, we no longer need to test td_waitset.
  now td_waitset is only used to give a thread higher priority when
  delivering signal to multithreads process.
  This also fixes a bug:
  when a thread in sigwait states was suspended and later resumed
  by SIGCONT, it can no longer receive signals belong to waitset.
