Summary: raw_input does not flush stdout

Initial Comment:
I know this has been talked about before. I am curious as to why it has 
not been fixed.

raw_input does not flush stdout before reading from stdin. This is a 
problem because if stdin and stdout are not terminals, then stdout will 
not be flushed, and the "user" will not know when he is being prompted.

Of course, I can use -u at the command line for python, but I don't want 
everything flushed every time stdout is written to. I only want it flushed 
when it is waiting for input. There is the potential for a large amount of 
data to be transmitted, and flushing everything can slow it way down. 
(Imagine 1000's of print statements, all flushing after they are done. 
Silly, isn't it?)
