Ge,

THANK YOU for coming up with something! I love this idea, because it 
gets rid of the memory problem, which is what mostly bothers me.

However, there is another one: gcc makes ntoskrnl 1.3MB with 
optimizations on and rsym "Stripping" the symbols.
However, building with -s and then doing strip -x creates a 530KB file 
(this is what msvc would produce).

If we can somehow remove the 900KB "gcc bloat" and keep the symbols, I 
will be very happy (And the users too).
The main reason I'm not so happy with the symbols is that we can't strip 
the files (afaik). The extra 800KB isn't symbol data...
