[stdlib-sig] socket.makefile() questions

[Timothy Bower]

fd.flush() seems to be the secret - worked as expected in all tests.  If possible, I'd like to suggest that the documentation be updated to explicitly say that a buffered file object is returned unless the buffering parameter is set to 0 (zero).  Setting buffering = None (default value) still returns a buffered object, which seems a little counter intuitive, but acceptable if the documentation makes it clear.

Thank you.

You are correct that fd.flush() makes a difference.  I thought that flush() would only affect the ability to read after the write, but actually the data was not sent until the flush() operation.  I'll do some more testing.

Thank you.

Have you tried fd.flush() after writing your data?
