That depends on what you want. If you call close() or 
disconnectFromHost(), QTcpSocket understands you want to immediately 
disconnect after finishing the connection.

In other words, the following is valid:

	socket->connectToHost("somewhere", someport);
	socket->write("Hello, world");
	socket->disconnectFromHost();
	socket->waitForDisconnected();

That will connect, write and disconnect.

A real use-case scenario is an HTTP/0.9 client:

	socket->connectToHost("trolltech.com", 80);
	socket->write("GET /\r\n");
	// don't call disconnectFromHost, the server disconnects us
	socket->waitForDisconnected();
	qDebug() << socket->readAll();


If you want to disconnect immediately, instead of completing the cycle, 
you can call socket->abort(). That should work in any Qt version, barring 
obviously if any bugs exist.
