Found a leak bug, this time in IE using the document.write/__ie_init hack to use $(document).ready(). Drip reports that this element is leaked using jQuery 1.0.4 (I've got IE7 running on XP SP2):

 
<SCRIPT id=__ie_init src="//:" defer __drip_hooked="true"></SCRIPT> 

This simple patch fixes it without affecting $(document).ready():

                        };

                // Clear from memory
+               script.parentNode.removeChild(script);
                script = null;

        // If Safari  is used

I can't think of another way to prevent the leak...but feel free to fix this however you see fit! :)
