Long polling ajax issue

Question

I have set up a polling script which basically checks the notification_queue if any new notifications are available. If they are it will display them and delete the notification from the queue.

I'm using firebug and when I reload the page the previous poll stays open and a new one is created.

        function poll(){
        $.ajax({
            url: "test.php",
            dataType: "json",
            complete: poll,
            timeout: 30000,

            success: function(data){
               $.gritter.add({

                    title: 'This is a regular notice!',

                    text: data.message,

                    image: 'http://a0.twimg.com/profile_images/59268975/jquery_avatar_bigger.png',

                    sticky: false,

                    time: ''
               });
            },
            error: function(){
                alert("OMG ERROR");
            }
        });
    };
    poll();

I am pretty sure the reason is that you pass poll as the complete function, effectively creating a non-terminating or cascading recursion (don't know if that is the proper term from programming 101 ...)
