I believe someone mentioned this possibility in the thread, and Linus said that it is much more possible now than it was before rmap, but that rmap isn't actually quite complete, so there are pages you couldn't move. He seemed open to an implementation, but the poster of the original patch says making kswapd do a better job of making space is orthogonal to making kswapd keep trying until it actually makes space, and not what he's working on at the moment.
