No, I mean that once we actually remove a page, we should also remove
all the other pages IF the file has never been accessed in a
non-sequential manner.  The inactive management is separate.

It's an optimisation in CPU time as much as for anything else: there's
just no point in doing expensive memory balancing/aging for pages
which we know are next to useless.

Cheers,
 Stephen
