I had been investigating this when I have time.   There are clearly  
many CFNetwork objects being leaked, but there are also a number of  
WebCore datatypes being leaked as well (StringImpl's being the first  
that I noticed), but the object graph involved is quite hairy so it's  
hard to pin down which object is the root of the leak.  Based on the  
pattern of data in the leaks output I suspect there are likely to be a  
number of distinct leaks.  I plan to dig in to these some more later  
this week.
