Ultimately, it would nice if Kaffe's JIT was smart enough to produce
machine code for stuff written in Java that was just as fast as C code. 
So given that, I think my personal preference is to see a Java
implementation whenever possible.  In certain cases, it might make sense
to implement things both ways - once with a pure Java implementation,
and once with a native implementation, and make it a configuration
option.  That would be especially nice, since we'd be able to "bake off"
the two implementations (which would be especially fun for the JIT
enthusiasts out there).
