[Python-Dev] PEP 371 trunk implementation

I've uploaded the first "rolled up" patch against trunk for PEP 371's implementation. This includes docs, tests, module, the works. The only outstanding issues with this are: * Had to comment out several unit tests due to threading._Event and multiprocessing Event API differences. * One test failing consistently on OS/X due to a change that came with rolling into trunk, I'm working on this * Bug http://bugs.python.org/issue1683 needs to have the patch reviewed and applied to trunk. * Full doc-content review The patch is both on the codereview system and the bug tracker: http://bugs.python.org/issue3050 http://codereview.appspot.com/2061 -jesse
