[issue6366] rare assertion failure in test_multiprocessing

[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

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>
  b785a08c:       refcount=2
    <multiprocessing.pool.Pool object at 0xb785a08c>
