Why doesn't quit_flag get set?  That's how I think we ought to do
this.  Avoid immediate_quit, that's dangerous to mess with.

I'm not sure why you'd want to use a target SIGINT for this case.
If we're between steps, we should just make sure we don't send
another step.  I suppose I hadn't thought about the case between
stepping and waiting...
