statsmodels has been using conda on Travis for a while now. I don't
remember seeing any problems related to downloading, so I never paid
attention to whether we download on each testrun or not.

(Also, we still haven't switched to the new Travis infrastructure. )

In the Travis log, conda reports that it's downloading around 200 MB for
that test run.
