Reference: python.org/sf/553736 There's been a request to backport the pthread changes made in 2.2 to the 2.1.x branch. Is any of the new (or old?) developers interested in helping out with this? It *may* be a simple backport, but I'm not sure -- the code is too full of #ifdefs to tell. --Guido van Rossum (home page: http://www.python.org/~guido/)
