I'm not an expert so I try to explain my scenario.
The server runs an async accept on a thread with basically the following 
code:

    boost::asio::ip::tcp::endpoint endpoint = 
boost::asio::ip::tcp::endpoint(boost::asio::ip::tcp::v4(), iPort);
    acceptor.open(endpoint.protocol());
    
acceptor.set_option(boost::asio::ip::tcp::acceptor::reuse_address(true));
    acceptor.bind(endpoint);
    acceptor.listen();
    TcpSessionPtr connection(new TcpSession(io_service));
    acceptor.async_accept(connection->getSocket(), 
boost::bind(&BoostTcpSocket::handleAccept, this, connection, 
boost::asio::placeholders::error));

in the handleAccept() callback a new async accept is called to allow the 
server to be able to accept other clients. Here is the code:

    TcpSessionPtr connection(new TcpSession(io_service));
    acceptor.async_accept(connection->getSocket(), 
boost::bind(&BoostTcpSocket::handleAccept, this, connection, 
boost::asio::placeholders::error));

So, it sounds reasonable that if the application ends an async accept 
operation may be pending. Now, how could I cancel a pending operation? 
Is there another way to solve the problem?
