I think if you add a return in g - outside of the handle() call - it will just be returned. It will however be returned both the first time when called (and starting to unwind the stack) and the second time when restarted (after reconstructing the stack). You could tell which of those you are in using EmterpreterAsync.state. Might be nicer to add an API for that.
