With the new task-notification indexes coming soon, I wonder if anybody else sees value in possibly adding a new configuration setting configSB_NOTIFICATION_INDEX which would control the notification index used by the stream buffer implementation. Thoughts?

If there is interest, it would be a very easy change to make. Currently the stream buffers use index 0 for backward compatibility, but configSB_NOTIFICATION_INDEX can default to 0 if undefined for the same effect.
