IMV, this has some slight value as it stands, although perhaps not enough
to justify a patch this big. The idea is that with this much in place,
patches to implement more aggressive and incremental maintenance of the
MV data become possible. So I think the bar it should pass for commit is
that it seems a sane basis for that, while providing some functionality
which people will find useful.
