Don't be so sure.  I have seen a beta test version of a compiler
I can't name yet that gives the following results:


				Lattice		"Brand-X"

	with registers		459		1041
	without registers	454		980
	with reg, file size	15680		5648
	without reg, file size	15724		5808
	boink + dry (regs)	112		236
	robocity + dry (regs)	184		403


The file size differences may be due to symbol table sizes or some other
factor.  I didn't investigate.

The "boink + dry" results is with boink running in the top half of the screen
and a cli window in the bottom.  There was no perceptable degradation in 
either the sound or speed of the ball.

The "robocity + dry" was with robocity running in the bottom half of the 
screen and a cli window in the top.  Note that under these conditions
"brand-x" gave almost the same drystone results as the lattice version with
nothing else running!.

One interesting result is that boink is apparently much more of a CPU
hog than robocity.
