[Interest] Qt Events/Signals and Loops (while ... for..)

As others have stated, you probably don't need to start a separate
thread for handling messages over your TCP socket (provided you're not
doing some computationally heavy task while processing your msg's as
that would stall the GUI thread). The asynchronous nature of Qt
networking makes it easy for you to just listen for signals (from
QTCPSocket) and react to them in a slot (in your main thread).

If however, you _do_ need to have a separate thread, read this article
first on how to "do it right"! :)
