It's often a desired behaviour: paging out unused memory makes room for a bigger page cache, which yields better performance. Also, it's a simple heuristic to know which pages are actually in use. Linux has a systcl that can be used to tune the swap tendency (vm.swappiness). Anyway, since it seems to improve performance under some workloads and it's just a constant, I've applied your patch.
