I don't want to make any more promises that I can't keep, but at this rate it is indeed looking good. However, keep in mind that while Morphzone loads, most other sites I've thrown at it still crash, so there's plenty of things to debug still.

Also, this is only the first level ("baseline") JIT, which isn't that much faster than the interpreter. I haven't started work on the second level ("DFG") yet, which will no doubt have its own set of problems to figure out.
