Yeah, that sounds like a serious flaw in OSX (one of many), even on very slow
Linux box I can run 100000000 uselocale calls in a second.
If uselocale is so slow on OSX, then it doesn't surprise me they wanted to add
functions like localeconv_l, but the whole point of uselocale is that it is
very fast and *_l functions are there mainly for APIs that are often
implemented inline and just dereference some data pointed by the locale_t
handle.
