Why not just fire off a few RST segments?  If you see a segment fly by,
it's really easy to synthesize an RST segment to blow away whichever
end of the connection you please; all you have to do is make the
sequence number correct.  (This is easiest when you want to RST the end
that sent the segment you eavesdropped on.)
