I suspect the onboard GX (cg6); if he's not familiar with kernel building,
RASTERCONSOLE is turned on, otherwise not.
Seeing as I get the same thing with RASTERCONSOLE off on _my_ IPX,
I'm willing to bet it's a deficiency in the interrupt code on the
onboard GX.
It is interesting to note that JOVE/EMACS do not suffer from this same
problem.

Theorem #1: There are several ways to create a quantum black hole.
- Butter a piece of bread and tie it, buttered side up, to a cat's back.
- Launder any number of matched pairs of socks.
- Divide by zero. Someone will disappear. It might be your lucky day.
