This is due to the fix for issue21090, which aimed to un-silence errors which previously went unheard. The fix is for me, as a user, to write a loop that uses os.read and interpretes EIO as EOF. This is what I had hoped file.read() would do for me, however, and what it used to do in previous pythons.

There's no reason for read() to interpret EIO as EOF in the general case: it was masked in previous versions because of a mere bug. The behavior is now correct, although being able to retrieve the data read so far in case of a buffered read could be useful.

Every change breaks someone's workflow. http://xkcd.com/1172/
