I was very much in favour of a longer period so that people like you could commit their changes. On the other hand, I think that the breakage will be relative, and it will be less for SP systems than for SMP systems. Certainly I think that Matt and I need to get our act together (i.e. a system which at least limps) before we commit anything; possibly people were a little too optimistic about how quickly we could do things when we broke up on Friday. > Also, what if the new MP core goes in and one or more of the key > players all of a sudden have no time to finish this due to unforseen > circumstances?

But I do think that we're entering a new phase of software development with this project: for the first time we have a project manager (Jason Evans), and I'd expect him to drum up some support, from BSDi if necessary. Note that Chuck Patterson is slated to help us with 50% of his working time until we get this rickety framework to fly.
