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. Thanks, M. -- Jazz is not dead. It just smells funny...
