I am unable to reproduce locally (over 500x iterations), and I have no clue 
what's going on: the warnings there aren't the problem (that's the main reason 
why we use the subprocess, to silence those). Do you have a local reproducer or 
is it only on travis? Afaik, there are no other reports of this test failing, 
are you sure its not related to changes on your branch?
