New submission from Nikolaus Rath:

It is currently not perfectly clear what Python (and the standard library) assumes about file-like objects (see e.g. http://article.gmane.org/gmane.comp.python.devel/148199).

The attached doc patch tries to improve the current situation by  stating explicitly that the description of IOBase et al specifies a *mandatory* interface for anything that claims to be file-like.
