Change 61088 by jmallett@jmallett_toxic on 2004/09/06 11:32:00

	Wild-assed guess after having not gotten to think about MIPS
	for a while- maybe I need to be more judicious about flushing
	out the cache?  I dunno, what with ASID tagging, but it's worth
	getting this thought out even if I can't test it, in trying to
	figure out why cached stuff goes wrong even though it worked at
	first.
