There is something easier to change. We could make Linux:
- age buffer and cache pages
- not age usermode pages, so it swaps them immediately
- flag the swap area as 'fast', so Linux doesn't swapcache
that area and it swaps more kilobytes to that area

That way, your upper 8megs will be used more frequently
and efficiently.
