Igor, thanks for your patience.

You are right, the piece of code I posted does not block the thread. May
be it's better going back to the test I posted at first:

    Server server;

    Client client;
    TcpSessionPtr connection = client.connect(host, port);

    bool accepted = false;
    boost::timer timer;
    while (!accepted && timer.elapsed() < 1.0)
       accepted = server.accepted();

Here the Server class derives from TcpSocket and the
acceptAsyncOnThread() basically calls the code I posted in the prevoius
email including the thread. The server.accepted() returns true if the
callback of the accept_async is called (and it works correctly indeed).
The process is blocked by a loop with a timer (as you can see from the
code). I would be glad if you could find the error in that code.
