ksm and mergemem

KSM is essentially the same idea as mergemen, which was developed about 10 years ago. This is not just useful for virtual machines, but also for ordinary multi-user machines (as explained by the lwn-reading example), and that's what mergemem was developed for. Unfortunately for mergemem, RAM was cheap, and few people in the Linux community seemed to be interested in multi-user systems. Maybe with the current interest in virtual machines KSM will fare better.
