I don't think grep is a very good candidate for O_STREAMING. I
usually want the stuff I grep to stay in cache. O_STREAMING is
much better suited to applications like ogle, vlc, xine, xmovie,
xmms etc since there is little reason for the OS to cache things
like songs and movies you aren't likely to hear/see again any
time soon.
