There is still some work to do. A number of bugs, some design issues,
and in general a lot of tidying up to do. If you want this in 4.5,
you're going to have to address this quickly.

But quickly doesn't mean rushing it, and I have the feeling that this is
what you've done over the past week. Also, I've reviewed this series 3
times during that time, and I feel a bit exhausted.

So please do not send another one before the end of the week. take the
time to address all the comments, ask questions if needed, and hopefully
I can review it again next Monday.


Jazz is not dead. It just smells funny...
