Thanks. I committed two of your commits in this PR as f59aa7d and 043dfef. I also added my own 63b10be to reduce some duplicated logic.

I didn't merge the travis_wait changes because, based on your comments, they don't solve the problem of the tests timing out. Let me know if I misunderstood.

Thanks a ton for doing this work!

They actually do, but the tests that around 30 minutes. So using 30 minutes sometimes worked and sometimes didn't. That's why I ended up setting the limit to 60 minutes which is higher than the total build time allowed by travis.
