Code review comment for lp:~pwlars/uci-engine/tr-pass-no-tests

We discussed going ahead and landing this in the call this morning. I was blocked on the tests because they didn't work right, and now blocked on getting deployment working with other dependencies on a (now worked around) change to make booting nova instances work with the new cloud we use. So there are a lot of things making the tests difficult for what would be an otherwise obvious change. I'll talk to vila when he gets back and once we get the other things sorted out I can modify the tests so that they expect the new behavior. It's just not easy to actually see them work right now.
