Speaking from a non-kernel-hacker's point of view, I think the requirement
for the pageable KPE is to reduce the number of pages that get dumped
on a crash (a la SunOS 4.x), which I think is quite reasonable.  I don't
think I have 64MB of important information active when my machine goes
down.

If it helps the merged buffer/page cache bit, so much the better.
