我最近阅读了objgraph文档,我对以下代码感到困惑

>>> class MyBigFatObject(object):
...     pass
...
>>> def computate_something(_cache={}):
...     _cache[42] = dict(foo=MyBigFatObject(),
...                       bar=MyBigFatObject())
...     # a very explicit and easy-to-find "leak" but oh well
...     x = MyBigFatObject() # this one doesn't leak

它表明"非常明显且容易找到'泄漏'".这有内存泄漏吗？这是dict _cache吗？
