Just got the following non-reproducible failure in test_multiprocessing
on py3k. Python was compiled in non-debug mode so I assume the strange
failure message is a multiprocessing feature?

8e25dcc:       refcount=1
    <queue.Queue object at 0x8e25dcc>
  8e25f6c:       refcount=1
    <threading._Event object at 0x8e25f6c>
  8e3774c:       refcount=1
    <queue.Queue object at 0x8e3774c>
  8e377ac:       refcount=1
    <threading._Event object at 0x8e377ac>
