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.
