It's not all that difficult, actually.
You can just connect the finished() signal of the QThread to the 
deleteLater slot of the object you have as your worker in your thread. 
Since Qt 4.8, that is save to do. All you need to do then, is if you 
quit your application (or the part where this is relevant), you also 
call quit() on your worker thread.
