On Windows with a PipeConnection object you should use rebuild_pipe_connection() instead of rebuild_connection().  With that change, on Python 3.3 I get

    <multiprocessing.connection.PipeConnection object at 0x025BBCB0>
    (<function rebuild_pipe_connection at 0x0262F420>, (('\\\\.\\pipe\\pyc-6000-1-30lq4p', 356, False), True, True))
    <multiprocessing.connection.PipeConnection object at 0x029FF710>

Having said all that I agree multiprocessing.reduction should be fixed.  Maybe an enable_pickling_support() function could be added to register the necessary things with copyreg.
