Yeah, I have this problem at work too, we actually have a separate 'chmod'
step that runs before the update/checkout. In our case it comes from some
test cases that exercise "what happens if I can't write to the file"
situations by doing 'chmod 0' on those files, and then sometimes fails to set
them back again.

Does anyone know what the windows equivalent is? Or can I just do os.walk and
os.chmod and expect it to be cross-platform?

I've created http://buildbot.net/trac/ticket/29 to track this one.

cheers,
