While it's true speed was not a priority, I think most of those initiatives didn't try hard to work with upstream. The Microsoft funded project is different, they're merging things. I don't think they've started on a JIT translator yet, though, last time I looked they were busy picking lower-hanging fruit. From watching their communications, I think they might get there at some point. It's not as simple as just emitting machine code, though. To get something in the same magnitude of typical C code, you need to deduce types and peel away the boxing and unboxing layers.
