I have the same mixed feelings.  I hope that in the future we can stop
deprecating/tearing apart old stuff without a good explanation of what
was wrong/unfixable with the old design, and a good design for the
future so everyone can help in validating and fixing.

Some important things that could be clocking-related (but nobody seems
to be able to tell) are still not fixed (mpeg playback, next/next in the
player, ...).
We should decide to either revert to the old situation (the enemy we
know) or make sure these bugs get fixed ASAP and we have a decent design
for it that more than one person can understand.

Agreed.

For the record, 0.8 is slated for beginning of march.
