We don't want to get stuck in BBQ forever in a long running loop. I think architecturally it'd just be best if we compiled a single BBQ Air Callee. That Callee can support OSR entering at certain loop boundaries. Perhaps we can implement it via entry switch. If we do that, this problem solves itself.
