A close term is "multithread-safe". The API could be implemented in a

It is planned to provide a multithread-safe implementation at some point?
My plan has been to add them eventually to glibc, where they would be
multithread-safe. It'd be nice to also make them multithread-safe in
Gnulib, so long as that doesn't make them harder to use with existing
apps, all of which currently use these functions only in a single thread
(which is why this is low priority). The only platform I know that
currently has them is NetBSD, where I believe they're multithread-safe.
I took the word "reentrant" from the "_r" suffix, which as you note is a
bit of a misnomer here (though a widely used misnomer...).
