[arty] 13732: Fixed more socket close problems. You could get through TCPClose, unlock

Fixed more socket close problems.  You could get through TCPClose,
unlock
the socket, have somebody else service and even, and unlink the
connection
object at the same time.  Now we hold the TCP lock while removing a
connection.
