Unfortunately, this did not solve the problem.

Setting swappiness to 0 and re-enabling my swap nearly immediately caused
the whole computer to lag whenever firefox had focus -- and swap use
jumped to 380M, despite having roughly five gigs free space.

Turning swap back off again helped immensely.

Thanks
