A patch for this will be out later this week. Probably tomorrow, but maybe even tonight...
The looping behaviour is easily fixed. If kswapd is looping, it means that we're out of memory and that try_to_free_page() is failing. That means that we can easily test for OOM when kswapd starts failing --> looping solved.
Then there's the question of whether we should kill a random process or a non-random one. When looking at it strictly, there's hardly an argument for the "I want a random process killed" folks, since a non-random one is just one of the choices the random process killing routine could have made...
The patch will be available from my home page, just like the scheduler bigpatch I posted today.
