	Thanks for the tar pointer.  Got to copy over /home here to
	the new box and run several into /usr/tmp.  Thanks to everybody
	for ideas.  I don't want to stress things until something
	*melts*... but some reasonably hard use.  I'm using three or 
	four benchmarks, and a couple of my own tests.  xload and top
	show that the results are a fair simulation of real-world use.
	Should know by the 22nd!
