// Buffers and sockets are now flushed when we shutdown the server rather
// than in the server's destructor. This removes the need for us to flush
// them to ensure we get the notifications.

// Changes due to the thread event changes and default worker thread
// implementation.  We now only have to derive from the socket server,
// rather than from socket server and worker thread and all notifications
// come via the socket server base class.
