Perhaps you are attacking the task from the wrong angle? I think that
sounds like a very tedius and error prone strategy. Why not refactor the
interpreter so you can instantiate it with an empty state in a separate
thread? I don't know; I am perhaps wrong, but isn't it more safe
strategy to isolate the state in their own threads instead of trying to
interloc bunch of stuff all over the place?
