It uses mmap() under windows. (I'm not an expert, but this is what I was 
said by others.) I did not know that multiprocessing can be used over 
TCP/IP. :) Probably I'll use zmq instead, because it has other nice 
features (auto reconnect, publisher/subscriber, multicast etc.)

As far as I know, POSIX compatible shared memory does not exist on 
Windows. I remember a thread about this on the PostgreSQL mailing list - 
the Windows version of PostgreSQL somehow emulates shared memory too. I 
wanted to use shared memory because response times are much faster than 
TCP/IP.
