Currently browsers (Opera, Firefox, Chromium) reconnect when they loose their
connection. Opera only tries a few times and a very short time, whilst Firefox
retries for around 15 minutes before giving up. Chromium keeps it going
indefinitely.

They do an exponential increase of the wait time. Up to a max. A smarter
implementation would also listen to "network up" events from the OS etc.

As discussed in the email threads ([3],and in [1]), it would also make sense to
notify of this state. In that way authors will be able to handle the reconnect
on their own if they want:

     es.onreconnecting = function(e) {
         // es.readyState is EventSource.RECONNECTING

         // We don't want the default behaviour
         es.close();
         do_custom_reconnecting_logic();
     };
