While I agree with this, I'm trying to figure out why this isn't being
incorporated into glibc instead..? Perhaps I missed it, but I didn't
see a discussion of that in the article. I'd certainly rather rely on
glibc if we can, though I know that we've ended up implementing our own
routines at times too. On the other hand, if there's a reason the glibc
folks don't want this, we should consider that..

Thanks!
