This is indeed something to look at. Maybe we could give
idle processes (sleeping for more than 20 seconds?) a
"full" swap_cnt instead of swap_cnt = rss >> SWAP_SHIFT ?

And we could also start swapping a bit earlier when the
cache is getting small, but I'm not sure about how to
do this or exactly what performance benefits that would
give ...
