But were you comparing against an earlier compiler with similarly
increased GC parameters?  That's the comparison that matters, and
I'm sure you'd lose that one.

I agree the defaults might not be "right", and that in a sense getting
them "right" improves the compiler.  But it's not really improved the
compiler, if you see what I mean.
