from an UX standpoint, it would be really good to have a loading indicator, visible after pressing the eval button and clearing the output box. this is a nice generator for a gif: http://ajaxload.info/

also, after about 10 secs adding a "still loading" text message and after, say, 30 secs cancel the call and replace it with a "server did not respond" message.
