bug#8961: stdbuf has no effect on some programs

Oops, please forget the statement about -o0. With the modified GNU libiconv
'iconv' program, -o0 does make a difference:
  $ (echo -n abc; sleep 1; echo def) | iconv
vs.
  $ (echo -n abc; sleep 1; echo def) | stdbuf -o0 iconv
In the first case, output is line buffered. In the second case, "abc"
occurs immediately.
