To my mind, the biggest problem with MGLRU is that Google dumped it on us
and ran away. Commit 44958000bada claimed that it was now maintained and
added three people as maintainers. In the six months since that commit,
none of those three people have any commits in mm/! This is a shameful
state of affairs.
I say rip it out.
