Heh. I still need to finish, and while I'm not sure I have any
planet-sized brains to bring to bear, I do now have defense of an ego
the size of a planet, which may suffice. :)

Java is something of a special case. The task of optimizing JVM code
is fairly non-trivial just given how much information is thrown out
by the compiler. (Stack-based intermediate targets are suboptimal
when you're looking to then transform to a register based target such
as hardware unless a lot of notation goes along with it which, alas,
isn't generally the case with JVM code)
