Well, the \r seems to be the problem, allright.
But output was not completely blocked, just delayed a very long time.
So perhaps flushing and a sending a newline aren't the only triggers for
output. Perhaps there's a maximum delay or a maximum cumulated size, and
the output is flushed when such a limit is reached.
Anyway, that's mainly academic. I doubt there will be a correction to
that behaviour.
