Agreed - at least "Unhandled exception".

I'm seeing, in the nosepipe code:
        # we use stdout for IPC, so block all other output
        self._stream = sys.__stdout__

I'm not sure using stdout/stdin for IPC is a great thing; a lot of
tests write to stdout or stderr, whether intentionally or
unintentionally.

I'm attempting to replace the use of stdout/stdin with os.pipe(), but
so far I'm not having much luck.  I get three write()'s, and then a
hang.  So far, I'm ignoring the fact that os.read() and os.write()
might split or aggregate chunks over a socket, since this is a
socketpair communicating on the same machine.
