Try "grep --line-buffered" to get grep to flush output after every
line. There is a performance penalty for doing this. I don't know why
you don't see the buffering when grep's stdout isn't redirected.
Perhaps grep (or the std library) removes/reduces buffering in the
case the output is a terminal.
