title: How to close boost asio server socket with all client sockets connected
body: <p>I use <a href="http://www.boost.org/doc/libs/1_37_0/doc/html/boost_asio/reference/ip__tcp/acceptor.html" rel="nofollow">boost:asio::ip::tcp::acceptor</a> to create server socket in my app. I close this acceptor socket using <code>close</code> function, than <code>stop</code> function in <code>io_service</code> but all connected client sockets closes only when my app is closed. How can i fix that?
  Thanks!</p>
