These ports are certainly inactive here - but it seems like GlobalDispatch
use the RST packets from the inactive ports...

I have stopped even these RST packets now. The result seems to be
much increased activity from DoubleClick :-)

I can see the possible need for what these people are doing, 
but as far as I am concerned they do it the wrong way.
