[issue15475] Correct __sizeof__ support for itertools

[Raymond Hettinger]

Raymond Hettinger added the comment:

The clean-up patch looks much nicer.  Thanks.

I'm not sure why anyone would really want this functionality for itertools, but I don't see any harm in adding it as long as the other implementations aren't required to follow.

Also, it could be viewed as being a new feature, so I'm not sure backports are warranted.  Be sure to ask the respective release managers before applying.
