Yet this happens not to be the case.
Did you try to put twice as much swap as you have RAM ? (e.g. add a 512M swapfile to your box) This is what Linus recommended for 2.4 (swap = 2 * RAM), saying that anything less won't do any good: 2.4 overallocates swap even if it doesn't use it all. So in your case you just have enough swap to map your RAM, and nothing to really swap your apps.
