	So you're proposing to drop support for machines with less than gobs
	and gobs of RAM?  Machines where -pipe thrashes bceause it can't keep
	all passes in core at once, and there just isn't enough RAM to dedicate
	to a large-enough MFS?

If you can't keep all passes in RAM then you're unlikely to be able to
keep the temp files cached in UBC either.  Those pages will probably be
reclaimed to run the next compiler stage.
