Agreed. There is an additional task which should be ready in August (sorry
it is taking so long but we have other priorities) and that is using the
Stack VM which is substantially faster (~ 20%) and a step towards the Cogit
which is a lot faster.
2) Changes to support Etoys and teaching for kids.

I'm currently working on some stuff that might affect this but there's no
guarantee that we'll release it. So I agree priority is low.
4) 64-bit FFI (Interpreter updates as well as FFI)
