Not as much as if it is buffered a la stdout (line if tty, else fully),
but still not nothing.  I change uucp with each new release to make it
line buffered; it requires adding fflush() calls in places so that you
can see send/expect strings in a timely manner.

Note that `tar tvf -' printed its `tv' output to stderr; this was one
of the worst offenders in the unbuffered stderr inefficiency game.  The
4.3BSD tar has been fixed (mostly by BRL) by making its stderr line
buffered.
