This should print two completions before 'callback', right???

bah.js

let g = newGlobal({newCompartment: true});
g.eval(`
    async function f() {
        debugger;
        await Promise.resolve(3);
        return "ok";
    }
`);

let dbg = Debugger(g);
dbg.onDebuggerStatement = frame => {
    frame.onPop = completion => {
        print(`completion: ${uneval(completion)}`);
    };
};

g.dis(g.f);
g.f().then(value => { print(`callback`); });
