What is happening is that no data is available in 'sshpeer.pipee' while the
command is executing. As the command completes, local output is printed, and
then sshpeer.cleanup() is called. When it calls 'self.pipeo.close()', the child
process is shutdown, flushing stderr.
As an experiment, I printed a line to stdout and another to stderr instead this
flush(). The stdout data was immediately available to the hg client, and none
of the stderr data was until the child exited. At that point, pipee has all of
the buffered data, and it is read out and printed before the pipe is closed in
sshpeer.cleanup(). This is probably a known issue, since ui.write_err()
mentions that stderr may be buffered, and also flushes stderr.
It would be nice if there was a more general fix (there is one more test that
fails), but I'm not sure what it is. I've seen (ancient) references [1] to
setvbuf() "crashing spectacularly" on some systems if any I/O has been done
already, so it seems worth avoiding.
