This simple script explains the problem:
<BODY onload="delete onload;alert(onload);">
The alert shows the event handler survives the "delete" operation. Also setting the event handler to "undefined" actually sets it to "null".

I'm not sure why setting the handlers to undefined fails, but it is correct behaviour for it to not be possible to delete the onhandlers.
