Just got this on py3k, I can't reproduce unfortunately.

test test_multiprocessing failed -- Traceback (most recent call last):
  File "/home/antoine/py3k/__svn__/Lib/test/test_multiprocessing.py",
line 1070, in test_number_of_objects
    self.assertEqual(refs, EXPECTED_NUMBER)
AssertionError: 10 != 1

there's not much I can do without the ability to reproduce it :(

Closed duplicate reports #6366 and #6747.
