For the buffer to properly act as an easy-freeable buffer
we will want to do the I/O based on the page table scanning
cycle, possibly with the addition of a special dirty list
we use for better I/O clustering.

It is a bit late for implementing it wholesale, but this
system certainly looks like something we can implement
piece by piece, completing (well, sort of) the new VM
system at about 2.1.10...
Only having the dual pass freeing and some very basic
balancing can be implemented now, the more advanced
balancing (to gain more performance), a better dirty list,
swap block layout and other stuff can be implemented
gradually. It is a pretty modular system, from a coder's
point of view.
I am willing to maintain some sort of patch series
bringing the efforts from multiple people together
if you decide you really don't want it in 2.2 now.
regards,
Rik -- slowly getting used to dvorak kbd layout...
