The point here is that there is no need even for that.
The full working set of files fit in memory with room to spare.
$ free -tm
total used free shared buffers cached
Mem: 1520 1035 484 0 41 605
-/+ buffers/cache: 388 1131
Swap: 1048 0 1048
Total: 2568 1035 1533
This is after 8 hours of uptime with firefox, evolution, an irc client
and an emacs running all the time.
It is the 484 MB in the free column I am after - that started out at
1062 MB this morning - I am looking for a way to turn of one of the
memory modules until it is needed.
