Here's a reproducible example:

  >>> import gc
  >>> import weakref
  >>> from Queue import Queue
  >>> class X(object):
  ...    def __init__(self, q):
  ...         self.q = q
  ...
  >>> x = X(Queue())
  >>> gc.monitorObject(x)
  >>> gc.collect()
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  RuntimeError: maximum recursion depth exceeded (Java StackOverflowError)

Here's where the infinite recursion from the earlier stack trace begins:
