Nothing is public. Regarding your comment about serialization: that's why I used websockets in the workers. It went pretty well except there was a bug in Chrome where the websocket in the webworker was still subject to the main loop. Something like that. Anyway, the point of offloading everything to webworkers was to make sure that the main thread is free for rendering. So there was very little to serialize, aside from dom differences which are generally not significant.
