/tmp on swap partition

Hullo! A fellow administrator of mine has his systems' /tmp directory mounted on a swap partition. It is causing odd behavior of several non-critical functions, but seems to be working. My question is, what benefit (if any) would such an arrangement have in Linux - or any Unix derivative? It seems mighty suspect to me, but then my experience is not as great as his. (ftr: He is not presently available for comment.) Thanks in advance for any thoughts on the matter. Rick Ireland You can run, you can hide... but in the end you'll only die tired.
