to stray entirely offtopic.

linux 2.4.10 contained a new VM, this AA VM (named after the developer Andrea
Arcangeli) was said to be much better than the stuff built by Rik van Riel.
This was the one big change of VM's in Linux 2.4. Since 2.4 came out people
moaned about the OOM killer (which kind of sucked, because most of the time
it would kill the wrong process). So now finally this OOM killer has been
removed and linux 2.4.24 will finally ship with a sane VM.

In 2.5/2.6 things are better organized with the Reverse Mapping VM from (again)
Rik van Riel,
