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();

or, if empty futures are allowed:

    future f; // empty/detached
    promise p(f); // attach p to f

This mirrors the future's ability to detect the lack of a promise object.
