 * A java.util.logging Handler that appends to a <code>Server</code> via

 * in practice it is used in a way that any thing logged on server is
 * transmitted to all remote clients, and even in wrong way; see below...

    // 2) serialization does not work (any more?) - remote client shows merely
    //    LogRecord@123456 instead of something meaningful
    // 3) When client connection gets lost, hassle with the isGone and logging
    //    of related information (still tried to send to client).
