What is if he isn't doing stuff quickly enough compared to the 
spending significant parts of the CPU just to dirty pages memory hog ? 
I imagine that the page scanning intervals  will be too slow, if 
you age more often you eat too much CPU [at least on Intel/SMP every pte
access is a locked transfer on the bus], if you do it too seldom
the memory hog can easily kill the system.
