I can produce a stable set of changes in the first patch set, but the fact of the matter is that much of the work is going to entail ripping out the SPL compatibility mechanisms one at a time and replacing them with mutexes. This will be an ongoing process over the next 6 months and that means that -current is going to be less stable for the entire time -- for both the SP and MP builds.

Right, and here I think we have the crux of the matter:

There is a lot of water between: "doesn't build, doesn't run" and "always compiles, rock stable"

And I think we can pressume that we'll end somewhere in the middle.

I am sure that all members of the SMPng crowd understand that leaving the rest of the FreeBSD developers stranded for more than a few days (worst case a week) at a time is simply not a good idea for anybody, right ?

I mean, the SMPng people will want people to beat the snot out of their chances and if people cannot built and run -current, how are they supposed to test it ?

So, Warner and everybody else: Calm down, nobody is closing the development in FreeBSD project down for half a year.

Matt and the rest of the SMPng crowd:

Give us some more concrete details.

Don't commit anything until people have had a chance to look at it and test it (normal procedure for large-scale changes applies 100% here) In particular a lot of people are at USENIX, nothing should be committed until they have caught up with their email.

And promise that you'll make sure that -current is usable as much of the time as possible for the rest of the developers.
