Threading was *not* deprecated Python 2.x or 3.x
Threading is for single process programs that want to emulate being multi-process while multiprocessing actually creates different processes. The multiprocessing module docs say:
"[sic]multiprocessing is a package that supports spawning processes using an API similar to the threading module. The multiprocessing package offers both local and remote concurrency, effectively side-stepping the Global Interpreter Lock by using subprocesses instead of threads. "
You can read about the multiprocessing module here: http://docs.python.org/library/multiprocessing.html#
