Summary: setvbuf for File object

Initial Comment:
I wonder if it is possible to add a new method setvbuf to 
File object.  The method does the same as the setvbuf() 
in stdio.h.

There is already an optional bufsize argument to file(),
open() and fdopen().  It allows you to specify unbuffered
(0), line buffered (1), system default (-1) or buffered
usage with a specific buffer size (>1).  Are you requesting
something different?

I see. Can you explain why invoking "python -u" is insufficient?

Sorry, I did not make myself clear.  I just want to be able to 
change the buffer size or the buffer mode of a file object. 
Especially, I often want to change the standard output buffer 
mode to line buffer so that I can see the result immediately 
even when the output has been redirected.

What buf argument would you like to pass?
