I've documented that exact case here: http://www.pixelbeat.org/programming/stdio_buffering/ There's a patch for `cut` there, which demonstrates how to add this functionality to coreutils. Personally I think it would be great to add the buffering control to glibc, so that most applications would benefit. But Ulrich Drepper <sarcasm>in his usual amiable style</sarcasm> suggested this was a silly idea.
