I'm not sure this particular issue was resolved completely. Mostly we
talked about read-ahead hints. The order-by-granulepos idea came out of
Jack's work on midi-over-ogg, I remember understanding that, but can't
recall the details. Maybe Jack can fill us in. I also remember talking
about order-by-granulpos-of-previous-page too, but that's not what
So, either I was stupid and missed something, or we have two
alternatives. One is that wildly-low-bitrate streams are an exception
to the ordering. The other is that (monty confirmed) itty-bitty pages
aren't expensive, so we can sprinkle the transcript packets throughout
the stream, sized to match the latency of the a/v streams.
