Unlike a UNIX fork, CreateProcess() does not have the same copy-on-write 
semantics for initializing the memory of the new process. If you want to pass 
data to the children, the data must be pickled and sent across the process 
boundary. He's not saying that multiprocessing isn't useful at all on Windows, 
just less useful for the scenarios he is considering here.
