Re: [boost] Do you know of standard implementation of async() that blocks on the future-destructor?

VS2015 seems to block in the future destructor of std::async, see the
output from the below program:

/M

Output:

policy: async
0ms (before)
3ms (async)
10008ms (after)
 -----
policy: deferred
0ms (before)
1ms (async)
10015ms (after)

Snippet:

  {
    std::cout << print_time(begin) << " (before)" << std::endl;

    auto future = std::async([begin]() {
      std::cout << print_time(begin) << " (async)" << std::endl;
      std::this_thread::sleep_for(std::chrono::milliseconds(10000));
    });

  }
  std::cout << print_time(begin) << " (after)" << std::endl;
