Failures on Master

[TomAugspurger]

This is under the "Allowed failures" section:

Started on https://travis-ci.org/pandas-dev/pandas/jobs/292375734 and is present in https://travis-ci.org/pandas-dev/pandas/jobs/292574197

https://travis-ci.org/pandas-dev/pandas/jobs/292375734#L2913

Probably from numpy/numpy#9487 (not a break on their part, we just have to update so a warning isn't emitted).

note, these are never actually allowed. this just makes the build run faster.
