Hopefully less flaky than after #204

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

@mattip, the following error in windows is flaky (and it's the first time I see it), but just FYI:

It's not that bad. It seems rare enough that I don't mind restarting builds to get past it. In terms of priority (from the POV of this feedstock), the 1.9 stuff is more important (and I believe more tractable too).
