Main thread doesn't respond to KeyboardInterrupt worker thread without user input

Very odd, posted a question below:

For now the effect is that the "Completed processing this tape" dialog doesn't show up until the user either hovers the mouse over the UI, or presses a key.

Quick look at answer to SA question: works, but once we activate the logger it throws a RuntimeError: main thread is not in main loop. Needs more detailed look. Maybe use queue for passing logging messages, see:

This looks like a better solution:

Works now!
