--- Comment #4 from 7WCbywQg3N2H@dyweni.com --- For what its work, I have been using these two patches (which I developed) with great success.
Using these patches, I can squeeze in one extra instance of Eve Online on my machine (each instance consumes roughly 1GB of memory).
The first introduces the KSM concept to select types of memory, and the second generalizes KSM to apply to all types of memory.
