[issue5700] io.FileIO calls flush() after file closed

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Yet one related bug is that flush() isn't called at all if the file was opened with closefd=False.

>>> import io, os
>>> class MyIO(io.FileIO):
...     def flush(self):
...         print('closed:', self.closed)
... 
>>> fd = os.open('test.out', os.O_WRONLY|os.O_CREAT)
>>> f = MyIO(fd, 'wb', closefd=False)
>>> f.close()

The proposed simple patch fixes both bugs.
