exit out of cpu_loop() and back to the caller can be honored. Previously, code in this function was a part of cpu_loop so a "return;" would already do that. Now, a value is passed back to cpu_loop() to denote such a request, and then a return is executed from cpu_loop(). I haven't tested this yet, but previously I must have broke certain debugging requests by moving the code to a separate function and not fixing the "return;" statements.
