I still have an unanswered question. There is code that I do not understand. It
is:

      if (pipe->Writers ++ == 0)
        PIPE_WAKEUPREADERS(pipe);

I cannot see how any readers can be on the pipe when the barrier was just
created in the open a few lines about. The patch fixes a problem, no problem
there, how-ever I am interesting why other code is even present.
