I like the essence of this proposal.  Two suggestions.  We can't achieve or
even robustly measure "everyone is happy with the code," so let's pick
concrete exit criteria.  Given criteria framed like "Files A,B,C and patches
X,Y,Z have a sign-off from a committer other than their original committer."
anyone can monitor progress and find specific ways to contribute.  Second, I
would define the subject matter as "bug fixes, testing and review", not
"restructuring, testing and review."  Different code structures are clearest
to different hackers.  Restructuring, on average, adds bugs even more quickly
than feature development adds them.

Thanks,
nm
