update buildbot masters to use build slaves randomly
Currently, builds are distributed to talos boxes sequentially (box 1 is always preferred, if it isn't available then box 2 is selected, etc). This can mean that box 3, 4, etc are never touched for tests that run quicker than builds are generated. We can also end up in bad states where box 1 is failing out quickly but then immediately served another build - consuming all available builds without managing to test anything. I'd like to more equitably distribute builds to test boxes using this patch: http://buildbot.net/trac/ticket/36
note that this will affect all other instances of buildbot on qm-rhel02, namely the unittest master and talos staging master (for now). This shouldn't be a problem. Are we going to apply this to the production branch?
OS: Mac OS X → Linux
We should go with the patch that made it into buildbot: http://buildbot.net/trac/changeset?format=diff&new=349&old=310&new_path=buildbot%2Fprocess%2Fbuilder.py&old_path=buildbot%2Fprocess%2Fbuilder.py
I'm taking this. I need to run this on the unittest staging environment for a day or so to make sure nothing breaks there.

somehow I missed installing this on qm-buildbot01. Below is the console output from a successful install.

Should see builds coming up on random machines now. Hopefully. Can we get this installed into BUILDBOT_MOZILLA_PRODUCTION?

This seems like it would be useful for all the masters used by build also. Can we also get this installed on staging-1.8-master, staging-1.9-master, production-1.8-master, production-1.9-master?

Even with two, dep builds would still only alternate between the builders (because they build continuously). It's a bit of a PITA to upgrade Buildbot right now so we may as well wait until we upgrade Buildbot on these to pick this up.
