Does the reply emit the finished() signal? I ask because I would expect the 
reply to either finish with an error or hang attempting to use the previous 
connection.

You could try using tcpdump or strace to check what QNAM is actually doing at 
the socket level. It might give more of a clue as to what is going wrong.
