	my problems with lockups seemed to initially only be in x, but now
	i think i have narrowed the problem down:

	basically, any program that uses more than a few hundred k of memory
	causes the machine to lock up [ in or out of x].

	i crashed the machine yesterday trying to rebuild the kernel, and
	today, trying to view some .ppm files from ray tracers and the like.

	when i say crash, it just completely locks up, and all activity and
	responses just stop.
