Florian has reviewed earlier versions of it with me, and it has two tests
which exercise the front end. Given this, I feel pretty confident about the
patch, overall.

I'm just waiting for reviews to come in on libc-alpha, and then I'll get to
work on a follow-up or check-in depending on the response(s). Carlos is
planning on reviewing it, so I should have some feedback soon. Of course,
I'll be happy to have your review if you have time to spare.

Cheers,
Arjun
