If it results in some form of improvement in performance, I'm all for it. 
I don't think we don't want a degredation in performance just to gain some
size benefits.  Though from past experience, it results in both size _and_
performance improvements for most code.

I'm of the opinion that we should definitely try it.

Too bad the "Summer of Code" thing is over.  This would have made a great
project for some eager coder to play with.
