I'd be even more confident if you don't disable the Python 2.6 OS X 
builder until a new Python 2.7 OS X builder is set up.  If this turns 
out to be easy, then nothing has been lost.  If it ends up being hard, 
then it's much better than having a screwed up 15.3.

Once again, I'm not really clear on why the existing build slaves aren't 
just being upgraded.  Why is new hardware required?
