The WG14 process is not fast.  It might take months to get any kind of
opinion.

To me, this change looks like pretty harmless -- it will add a few bytes
to the library, but no instructions on the critical path (assuming that
error returns are rare), and could help to avoid Heisenbugs.  There's no
API/ABI impact, so it seems like this is just a QoI issue.

What's the harm in putting it in EGLIBC without WG14 sign-off?
