With the proposed schemd you would have to move pages between lists if

lead to lots of pages moving to the unnmapped list.
That could be a problem.
Another problem is that any such heuristic in the VM is
bound to have corner cases that some workloads will hit.
It would be really nice if we came up with a page replacement
algorithm that did not need many extra heuristics to make it
work...
