As far as I can tell, there are no concrete plans to integrate
concurrency better, or get rid of the GIL, at the moment. 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.

There is, of course, Stackless Python.
