I had planned to write at least a blog post on this and related topics, essentially in how Cog coordinates an interpreter and a JIT, but I've not found time in 5 years :-/. I think it's important to write up.  I remember reading something about the Erlang VM wanting to do the same and they ended up having two separate stacks for interpreted and machine code frames, bad for a number of reasons. The stars may yet align and I'll write it up...
