I tried using multiprocessing.Pipe() and send_bytes()/recv_bytes() to 
send messages between processes:

   8 bytes messages  -- 525,000 msgs/sec
   15 bytes messages -- 556,000 msgs/sec

So the size of small messages does not seem to make much difference.

(This was in a Linux VM with Python 2.7.  Python 3.3 is much slower 
because it is not implemented in C, but gives similarly close results.)
