     Agreed.  UNIX/Linux/Python interprocess communication is inefficient
compared to, say, QNX or Minix 3.  But where Python and XML are involved,
you've already lost 2-3 orders of magnitude in performance over something
like MsgSend in QNX, or even OpenRPC.  So don't worry about the socket
overhead.
