Cool stuff! Can the branch be actively used or is it still too incomplete?

Since Justus took a full time job, he had little time to pursue his
work, and I stepped in to finish it. After a few months of occasional
bug hunting, I finally got a working version that you can find in my
darnassus repository [1], branch rbraun/vm_page.

My approach was to redo the work with the least possible assumptions,
something that is actually very hard to do as it took me a lot of time
to identify even the slightest ones that turned out to be wrong. This
work isn't finished, it's merely an incomplete development branch,
but it's an important step towards managing more physical memory and
very strongly reduce kernel memory exhaustion panics.
