Can't help with that, but surely Windows has some thread-safe way.

What I can tell you about that is that check_locale's expectation
that setlocale does any useful canonicalization is mostly wishful
thinking [1]. On a lot of platforms you just get the input string
back again. If that's the only thing keeping us on setlocale,
I think we could drop it. (Perhaps we should do some canonicalization
of our own instead?)
