> Another possibility is for stop() to change conditions so that '' fails with an exception

Could you elaborate? Since there're no docs on event_generate(), I can't look up how to make it "fail with an exception" without actually posting an event.

> The only problem is that the first t.join() hangs because of a thread deadlock bug.  t.join() blocks until exits. does not exit until the last event_generate, with running=False, returns.  But that blocks until dummy_handler runs.

The idea is to let the worker threads finish their work, not terminate them forcibly.
So the real problem is that stop() blocks the event loop.
It should rather run asynchronously, wait for threads, then trigger `self.root.destroy()` in the main thread... somehow.
