Logs a lot more things, and gives up if the initialization of the ZygoteWorker fails rather than infinite-looping. The ZygoteIOLoop stuff is pretty janky, but tornado is very insistent about logging to the root logger unless you give it a solid thwack on the nose. As I put in the XXX comment, I'd like to do something similar for RequestHandler, but I'm not sure where a good place to do so is.
