• Spawn a QThread.
• The QThread can farm out tasks to the multiprocessing Pool. You might use pool.apply_async() which has a callback parameter.
• The callback parameter allows you to specify a function which is called when the target function completes.
• The callback runs in the QThread, and is sent the return value of the target function as its one and only argument.
• Each time the callback function runs, you can update the GUI to indicate the progress.
