IMG onload reassignment

Hacking on a dojo dijit widget today I came across some strange behaviour that only seemed to happen in IE. Turns out the reassignment of an image node's onload was causing the new onload hander to fire. Here's the code that reassigns onload:
img.onload = function(){ self.onImageLoad(); }
IE is not open source so I can't diagnose exactly why the onload fires when reassigned. I worked around it by making sure that the premature firing would not be harmful.
