  Log:
  Fix pthread_suspend_np/pthread_resume_np.  For the record, suspending a
  thread waiting on an event (I/O, condvar, etc) will, when resumed using
  pthread_resume_np, return with EINTR.  For example, suspending and resuming
  a thread blocked on read() will not requeue the thread for the read, but
  will return -1 with errno = EINTR.  If the suspended thread is in a critical
  region, the thread is suspended as soon as it leaves the critical region.
  
  Fix a bogon in pthread_kill() where a signal was being delivered twice
  to threads waiting in sigwait().
