I agree, in general. My only question would be why branch 2.2 *now*?  
My only concern is it might be too soon and we'll be merging more  
changes from branches/2.2 into trunk than we'd like. Either way  
(branch now or branch in a week or two) I agree with the above.

Ah. So, I'd agree with that. Sounds like we're of the same general  
mind... Some general progress on the server TCK would also be valuable.
