Sure, I can see the argument for that.

I suppose the case against would be, perhaps the folks already listed
in the RECLAIM section don't want to additionally get e-mail for the
extra files listed in this patch? (Perhaps mostly the MGLRU
documentation, the rest of them aren't necessarily MGLRU specific.)

I don't have a strong preference either way, I think mostly I'd be
interested to know Andrew's or the other reviewers' preference. Note
Lorenzo suggested a separate MGLRU section here:
