* status: positive_review => needs_work
Comment:
There is now only the factorial remaining, but now for a different reason
then before:
sage: import gc
sage: import inspect
sage: l1=gc.get_objects()
sage: frames=[x for x in l1 if inspect.isframe(x)]
sage: len(frames)
9
sage:
l=objgraph.find_backref_chain(frames[8],inspect.ismodule,max_depth=15,extra_ignore=[id(frames)])
sage: map(type,l)
[<type 'module'>, <type 'dict'>, <class
'sage.combinat.species.stream.Stream_class'>, <type 'dict'>, <type
'generator'>, <type 'frame'>]
