To quote http://wiki.python.org/moin/GlobalInterpreterLock """Getting rid of the GIL is an occasional topic on the python-dev mailing list. No one has managed it yet.""" There are currently no open or accepted PEPs on the subject of concurrency. http://www.python.org/dev/peps/ There is, of course, Stackless Python. http://stackless.com/
