Union does seem to have some problems (_not_ personal experience, I
don't use it). Could you not just mount an MFS on /tmp and put all
temporary files there, with perhaps symlinks in known places pointing
to somewhere /tmp if you can't easily change the referenced path names?

I've been running my new pmax Xterm (formerly Ultrix) without swap for
a few days because I hadn't yet got around to setting it up yet. No
problems so far...
