- Hmmm. I have a 32 meg swap partition and 16 megs of memory on an SLC.
- Maybe the SLC is too slow. Or it might be the way we built lucid emacs

- Someone sent me a quick fix that involved defining the TERM
- environment variable and all worked well.

- I will need to go back and check how we built it. It is possible we
- never turned on the optimizer and only the debug flag. I'll check.

- No problem, it certainly won't stop me from using lucid emacs.
