I still think DNS caching in kio might be necessary. Long ago, I had the same 
problem with a page with many pictures on it, and konquerer did way too much 
DNS lookups. 

Of course this is a problem, even a small latency of 30ms for a DNS lookup 
will be noticeable if 650 requests are going over the wire.
