Ooooh. We saw something like this, specifically when doing a "swapoff -a". As >25Mb were swapped out, the command took a while to complete. From the time the command was issued, until swap did indeed die, we had 0kb total, 0kb free, and almost exactly 2Gb used(!).
Apart from that, pre-2.0.31 + 5 fixes + seriously hacked and finally stable 3x59x driver, is running like a treat under at times pretty hefty load.
Note that the sockets stuck in "CLOSE" I reported, are NOT a problem, and were related to a memory leak in an ethercard driver I hadn't patched with a "dev_kfree_skb".
