- Copy signal mask out before THR_UNLOCK(), because THR_UNLOCK() may call

  _thr_suspend_check() which messes sigmask saved in thread structure.
- Don't suspend a thread has force_exit set.
- In pthread_exit(), if there is a suspension flag set, wake up waiting-
  thread after setting PS_DEAD, this causes waiting-thread to break loop
  in suspend_common().
