Yes, that's what I mean.  Specifically, a real-world example where the
rejection handler is added in "some future turn", using a fuzzy definition
of that phrase.  A contrived example would be:

    // Create a future and get the resolver
    let resolver, future = new Future(r => resolver = r);

    // Reject it
    resolver.reject("error");

    // Attach a rejection handler 5 seconds later
    setTimeout(() => future.then(null, err => null), 5000);
