I no longer like future<>::cancel. :-) Have you considered the alternative of automatically invoking the cancel handler when no futures remain? This requires that a promise and a future be created at once:
pair<promise,future> pc = create_channel();
Would that really be necessary? Presumably, you would only want it to call the cancel handler when the future reference count makes the transition from 1 to 0, not potentially multiple times while the reference count sits at 0.
or, if empty futures are allowed:
future f; // empty/detached promise p(f); // attach p to f
