I'm not sure about this. If your seek terminated at one of these 
"duplicate previous packet" packets, wouldn't you still need to load the 
original Kate packet in order to render it? If the original packet isn't 
downloaded yet, what kind of operation is required to find it? Another 
bisection search over HTTP?
