Łukasz,
_closing is not necessary on FileIO instances. The class already declares an
__exit__ method which takes care of closing file.
>>> import io
>>> f = io.FileIO('/tmp/test_closing', 'wb')
>>> f.closed
False
>>> f.__exit__()
>>> f.closed
True
Since both IOError and OSError are direct subclasses of EnvironmentError, we
can use this in the except clause.
