Comment (by viboes):

 What would you expect from the following code


 {{{
 int main(int argc, char* argv[])
 {
    boost::packaged_task<int>
 pt(calculate_the_answer_to_life_the_universe_and_everything);
    boost::future<int> fi1 = pt.get_future();

    boost::thread task(boost::move(pt)); // launch task on a thread

    boost::wait_for_any(fi1, fi1);
    std::cout << "Wait for any returned\n";
    return (0);
 }

 }}}
