I don't generally like this idea because it is so easily fraught with various nasty usage issues - just looking at the file semaphore would probably make it fairly easy for somebody who knows how we work to come up with some programs that may not deadlock but would create some really pathological memory management behaviour. I'll think about it, though - together with some kswapd help we might well be able to guarantee that nobody will be able to cause problems by keeping a file busy.
