The native codegen just sends each MachineIL through the codegen passes 
one at a time, so it ought to be parallelizable. Of course, once you have 
multiple threads in flight, they are competing for the same memory (and, 
more importantly with multi-core, the same cache), so I'm not sure how the 
trade off would be resolved.
