    r79925 | nick.coghlan | 2010-04-10 16:24:36 +0200 (sam. 10 avril 2010)

    Try to turn some buildbots green by allowing test_multiprocessing to
    pass even if it hits the sys.exc_clear code in the threading module, and
    improve the test coverage by making the ctypes dependencies a bit more
    granular (two of the cited ctypes objects don't exist on my system)
