Do you think of something like http://bellard.org/jslinux/?

The current interpreter is built inside QEMU, and I'm afraid
that separating code generator and interpreter in different
processes might be a lot of work. Maybe running both in
separate threads would be possible, so the code generator
could prepare new bytecode while the interpreter is still
running the previous one.
