That's only true for LC_NUMERIC category.

GNU/Linux is the only one I know of that can efficiently switch
locales dynamically (and even that in recent versions of libc, AFAIR).

functions, so how does some buffer enter this picture?  Buffers don't
have anything to do with the locale used by library functions called
by Emacs.
