Completely agree. Even if you go ahead with these changes, they really should go through some kind of distro verification [1]. If I even contemplated such a change in glibc I'd run it through 4-6 months of Fedora Rawhide builds just to see what breaks before putting it out in a real release (and we do this frequently for thread-related changes). -- Cheers, Carlos.
