I'm not sure if this pickling stuff matters as long as they both pickle.

> The Python version of StringIO throws an AttributeException on the .name attribute.  It's a property inherited from the TextIOWrapper.  Effectively, TextIOWrapper provides the .name attribute if the object that it's wrapping provides the .name attribute.  This behavior is undocumented.

> Is that reasonable behavior?  Or should TextIOWrapper define .name always and return some suitable value if the wrapped object doesn't define .name? (e.g., None)

Yes, all the code expects an AttributeError on name is it's not
present. For example, FileIO only sets its name attribute if it is
passed a filename and not an fd.
