I have suggested a way to move the existing concurrency stuff without breaking backwards compatibility, and Terry Reedy asked if it would work. I haven't seen any responses, either positive or negative.

For the record, my suggestion was: for each concurrency modules: move it into the concurrency package add a top level module with the same name containing: # e.g. for threading from concurrency.threading import *

In the past the problem identified with this approach has been that pickles produced with new pythons would not be readable by older pythons.

I think this was the main reason that Brett's 3.0 library reorganization wasn't more radical. Theres a discussion if this here: http://mail.python.org/pipermail/python-dev/2008-May/079535.html http://mail.python.org/pipermail/stdlib-sig/2008-May/000303.html and a little more here: http://bugs.python.org/issue2775
