In that case, it doesn't even need to be thread-safe. libm is
supposed to be thread-safe, but has no need to be thread-aware.
ICU is different in that not only can it be called from multiple
threads, but those threads can (in theory -- as far as I know, you're
right that nobody uses this capability right now) be interacting.

On the other hand, that could change at any time.
Think of all the other programmers in the world as independent
threads, that could use the API in new ways... ;-)
