Note that you only get RuntimeWarnings with numpy master, not with a
released version (due to switching tests to 'release' mode).

That can always happen, those are usually harmless.

That's the casting='same_kind' I assume? We did that on purpose and thought
about it quite hard, so that's OK. If there are other, unintended casting
rule changes then I'm not sure.

Also not an issue, because they were added on purpose. I think those
warnings are a bit too intrusive at the moment, but that's unrelated to
Scipy 0.13.3

Sounds like we managed to not break anything seriously in numpy master
recently, so branching 1.10.x seems OK from this point of view.
