Perhaps we could make a smooth transition by implementing both methods
on our kernel, then update glibc to use the new one, and only remove
the deprecated method in our kernel after a full release cycle.

Petr, do you think this could fly? We'd be breaking backward
compatibility in userland, but if I understand correctly we do this
already and our only supported upgrade path is "first upgrade kernel,
then userland" anyway.
