Why is this milestoned for 1.5.1? This requires py2.7+ due to the use of OrderedDict().

[mdboom]

@WeatherGod: Thanks for catching. I was just thinking "bugfix", but you're right, we still technically support py2.6 on 1.5.

cherry-picked to 2.x as 4ca39f7

This doesn't appear to be working.

I doubt it is actually because of the test. The logs show a whole bunch of
other things going wrong while the font-cache is getting built. I restarted
one of the builds to see if the problem resolves itself.
