[jQuery] IE/FF Memory Leak

[optimalcapacity]

I am a newbie to jQuery so this may be a simple answer...

My goal in this exercise is to return a specific html table block
(table.DetailTable) from a dynamically generated html page which is
the result of a servlet call into a div (xyz).  The issue I am having
is that whether I set the timer interval to 1 second (1000) or 30
seconds (30000), this code is leaking horriblly.  I verified the leak
in both IE6 and FF 2.0.0.12.

Here's the abbreviate code snippet that I'm working with:

function loadMyData(){
var t;
$("#xyz").load("http://URL table.DetailTable",{Param1:"Param1Value"});
                        t = setTimeout("loadMyData()", 5000);
                }

$(document).ready(
        function(){
                loadMyData();
        }
);

Any help with this issue is very much appreciated!
