Hi,
after running your patch some time I have to say that the old VM implementation and the full rmap patch (by Craig Kulesa) was better.
The system becomes very slow and has to swap in too much after some uptime (4 hours - 2 days) and memory intensive tasks...
Maybe this happens only to me but it's fully reproducable
If you need some more informations just ask
Bye
