Disclaimer: I'm pretty terrible with multithreading, so it's entirely possible I'm doing something wrong. I've written a very basic raytracer in Python, and I was looking for ways to possibly speed it up. Multithreading seemed like an option, so I decided to try it out. However, while the original script took ~85 seconds to process...

When the reactor is shutting down, I have to: 1) check if the thread is doing things 2) stop it if it is What's an elegant way to do this?
