calling self.update() at regular intervals inside the loop (at least a couple
of times per second, if you can arrange that) will give Tkinter a chance to
process incoming events.

another possibility is to use a thread to do the processing, but that involves
other tricky issues (especially if you want to update the UI from the thread).
