No, that's not the recommendation. We're saying you don't *have* to use 
threads for sockets in Qt. Unlike Java sockets, Qt sockets operate 
asynchronously and in non-blocking mode. So you can operate them without 
resorting to the one-thread-per-socket approach found in Java.

Whether you need threads for other reasons, that's entirely up to your 
specific use-case. We can't generalise.

Of course.

Instead of answering, I ask you: why is using threads better?
