It looks like I need to send a v4 of this, since I renamed a Python 
class but forgot to update all users of it. I didn't notice this, since 
I had the old module lying around as a *.pyc file, so the old name worked:-(

I also have a couple of minor fixes to roll in that make the scripts 
work better under a continuous integration environment (which doesn't 
have a controlling TTY set when the scripts run, which need a minor 
tweak to the Spawn code).
