There are plenty of different IPC mechanisms available in
multiprocessing.

Take a look at:

- multiprocessing.Array and multiprocessing.Value

- mmap.mmap with 0 or -1 as the first argument (Windows and Linux,
respectively)

- pywin32 on Windows (not standard lib)

Unix domain sockets are called 'named pipes' under Windows. Look for
it in multiprocessing or pywin32.
