Yes. That's exactly the kind of meta-level protocol
that I propose in my thesis. Actually, it's a bit more subtle than that,
since the "abstract interpreter" must map the *state* of the stopped
*and synchronized* process running the compiled program into the abstract
computation that has been declared. Synchronization being necessary because
compiled processes (especially in a concurrent setting) have a lot of
transient states that have no coherent abstract meaning (e.g. abstract
invariants can be locally broken by the concrete implementation;
that's the well-known atomicity problem in databases).
