What I seeing is a series of approaches being put into the kernel to
address this issue. We already have the lumpy reclaim there. Then we talk
about other fixed to basic page handling in the kernel to make it better.
Now you want yet another fs layer. All of that could be taken care of by
a defrag approach with larger pages. This has been done a number of times
before and actually the large page approach is a textbook example on how
to improve performance. It goes waaaay back.

Dont worry you will get numbers... Just did not have time to fix the bug
in this one since I had to take care of something else.
