	Good grief.  I could be hallucinating, but it seems that 
	a make world finished in about 2.5 hours on this box.  This 
	is 3/4th GB memory and 700+MHz.  This was with 5.3 here.

	Does it make any sense to use O3 when compiling stuff,
	when stuff includes world/kernel/drivers?  Does upping the
	optimization make any significant difference in system 
	performance, in other words?  Kent?  Anybody?
