I'm seeing a hang on exit. I did a stack trace and a kill -3 on it, https://gist.github.com/4179325. It looks like the console input thread is hanging for some reason. Note this only happens when I type exit and enter. Using CTRL+D works, but CTRL+C does not either. It doesn't hang, but it doesn't exit with CTRL+C.
