Nobody did the work yet. If it's very important to you, consider spending effort making it thread safe. I believe netbsd and freebsd have thread safe implementations. But actullay verifying that is pretty hard.
Yes, the NetBSD implementation is thread-safe since 4.0. For FreeBSD, I don't know since which version it is thread-safe, but it's thread- safe in recent versions.
For the verifying part: If the implementation has no side-effects (like modifying some global variable that is not per-thread), the implementation is thread-safe.
