Thanks, that sounds great.

We should keep an eye on this.

Would you mind adding this to the release blockers for 2.20
on the wiki?

https://sourceware.org/glibc/wiki/Release/2.20#Release_blockers.3F

I know that 2.19 has already gone out with this change, but
we should still prevent 2.20 from going out if there is a
bug here that needs to be fixed.

Cheers,
Carlos.
