Simple jQuery Ajax call leaks memory in Internet Explorer

Here’s a link to the bug over on jQuery, along with this as a suggested fix for jQuery 1.4.2:

                            // Stop memory leaks
                            if ( s.async ) {
-                                       xhr = null;
+                                       xhr.onreadystatechange = null; xhr.abort = null; xhr = null;
                            }
                    }
            };

NOTE: This is officially fixed in jQuery 1.4.4, so your best bet is to just upgrade now.
