[issue7786] Is the BlockingIOError exception an aborted idea?

New submission from David Beazley <dave at dabeaz.com>:

Documentation (e.g., docstrings) for the io module make mention of a BlockingIOError exception that might be raised if operations are performed on a file that's in non-blocking mode.  However, I am unable to get this exception on any operation (instead None is returned for non-blocking).  Moreover, I can't find any reference in the C/Python source for the io module that ever raises this exception.

Perhaps someone can clarify the status of this exception?
