This is already fixed, so just rebasing your patch should resolve this one. :)

These two make total sense.

Sigh. Can you send us a patch that adds the extra case the regex match
for docker? There's no reason these tests shouldn't pass there.

I'd gladly take this for 4.2 and try to add building of linux wheels
to our release discipline, assuming they work correctly. How much did
you test the wheels by hand once installed?
