Summary: inspect.stack() refcount problem

Initial Comment:
The attached code exhibits the problem: Calling a 
function that assigns the results of inspect.stack() 
to a local variable causes an extra ref to objects in 
the caller's space. Not doing the assignment does not 
cause the problem.

Appears that the stack frame is disrupting the 
reference counting in some way.

Tested with Python 2.1 and 2.1.1

Your attachment didn't work.

But don't bother.  The behavior you describe is not a bug.
It creates a circular reference.  If you don't want that,
don't use
inspect.stack() or sys._getframe() (which is the same
thing).
