I see your point and can confirm this...  The problem seems to occur only when
the client is killed and effectively "orphans" the connection anyway causing
the timeout to have to end the connection on the server end.  I ran into this
debugging the client when I was abruptly killing it and restarting rapidly. 
Sorry if I wasted your time.
