Can you measure a performance degradation because of that? Previous kernels was certainly not a good example because they was swapping out stuff even with `cp /dev/zero .`.

You said me your machine start to swapout when the filesystem cache reaches 100mbytes (on your 384Mbyte box). That seems sane behaviour on a misc load. We could add some additional bit of page aging to swapout more when it worth indeed, but current balance looks just quite sane.
