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...).
