Hm... I'm not against this, but I actually had plans to write some
extensions and allow the main thread to do something else (this is probably
fairly vp9-specific), and this would prevent that. In vp9, specifically for
tile decoding, I'd like to use the main thread for 1 thing and the worker
threads for other things. Maybe we can make this configurable?
