I'm pretty sure you're after the vm.dirty_ratio and vm.swappiness
settings. Again, have a look at the kernel docs, I remember a very
useful doc in there that explained what the options were (as well as
being able to change the defaults when you build a new kernel).

I would prefer some middle ground, like a trip wire value that would be some percentage of available ram, rather the just leave like 80mb of free ram, on my now, slowed system.
