Sweet, thanks. I'll get on the Cython refactor today
 hmm…failing on travis for 2x but works for 3x, and also works on 2.7.3 locally…
 #2380?
 Not sure why that would work for me locally then.
 I had the same issue, there's a random.seed() call in the code, which when combined with
the travis image makes randint deterministic, and it just so happens that the seed triggers
the problem on travis everytime. that's my take on it, anyway.
I was able to reproduce intermittently locally, but it was somewhat rare.
 got it. thanks.
