I'm starting to think that going back and benchmarking my vm patches
against 2.1.47 or 66 might prove useful as they used a physical page
scanning with the old LFU technique, but proved remarkably faster than
scanning the virtual addresses space of processes.  Gee, I guess it's time
for forward port the beast again and see what results it gets against
current things.
