I can't get the concurrent stat example from http://pogoscript.org/2012/12/05/async.html http://pogoscript.org/2012/12/05/async.html to work. It doesn't do anything when run. I think it's exiting at the first async call. My shell session: http://codepad.org/xWoOrHpe http://codepad.org/xWoOrHpe How do I fix this?
