Looks good to me, though I expect we may want tests with this?

Any idea what's up with the integration test? For me they get also stuck locally.

I think the CI is fixed in #194. @abompard, are you around to review that?

[jeremycline]

Actually, current master also passes CI. Maybe one of the tests is expecting something from one of these exceptions that broke? I don't have time to dig into it today, but I might be able to in the next couple days.
