I just saw this issue again on 3.8.0-9. Current memory usage (after the swap storm calmed down):

vm.swappiness=30. The flash blocker extension is still in place in my browser.

It seems like the kernel is somehow unhappy to let its page cache drop below 1.2GB in size, and tries really hard to prevent that by swapping other things around?
