This looks ok trace this time :-), I changed the ordering of the lines so 
that warning was supposed to appear only after the wq print. Now it's just 
the hard par remaining, ie., I must figure out what was the state of TCP 
before the event the event... :-).

If you still get additional events (you could if a particular torrent 
peer is there having the same network behavior), please post them as well 
if they reveal something that helps exclude cases (if I don't right away 
get the idea :-)).
