                          thr_sigsuspend.c 
  Log:
  Check pending signals, if there is signal will be unblocked by
  sigsuspend, thread shouldn't wait, in old code, it may be
  ignored.
  When a signal handler is invoked in sigsuspend, thread gets
  two different signal masks, one is in thread structure,
  sigprocmask() can retrieve it, another is in ucontext
  which is a third parameter of signal handler, the former is
  the result of sigsuspend mask ORed with sigaction's sa_mask
  and current signal, the later is the mask in thread structure
  before sigsuspend is called. After signal handler is called,
  the mask in ucontext should be copied into thread structure,
  and becomes CURRENT signal mask, then sigsuspend returns to
  user code.
