Well, if you want your thread to interact with main app using signals & 
slots you need to have an event loop for each thread (and use 
moveToThread where necessary). That's what the QThread::run() does.

Yes, you call start() and run() is called. Remember that thread exits 
when run() returns.

Ah well, regarding the memory leak I did not look into the details so I 
have no suggestion.
