    Clean up handling of the signal pipe.
    
    I wrote into it in the signal handler, but forgot to read the bytes
    back out in the poll loop! Also the pipe wasn't set nonblock (without
    which _both_ those operations are fraught with danger).
    
    While I'm here, enlarged on the comment saying why the error check in
    the signal handler does nothing.
