  Modified files:
    lib/libpthread/thread thr_sig.c 
  Log:
  _thr_sig_check_pending is also called by scope system thread when it leaves
  critical region, we wrap some syscalls for thread cancellation point, and
  when syscalls returns, we call _thr_leave_cancellation_point, at the time
  if a signal comes in, it would be buffered, and when the thread leaves
  _thr_leave_cancellation_point, buffered signals will be processed, to avoid
  messing up normal syscall errno, we should save and restore errno around
  signal handling code.
