Sorry if I wasn't clear. Yes, a tty file will be buffered, but it's
line buffering, which isn't an issue as long as lines are written to
stdout. I was referring to full buffering of pipe and disk files. This
can be a problem when printing diagnostics. We went the information
written to the file immediately, not whenever the buffer happens to
fill up. Thus sys.stderr is unbuffered.
