I can't start with the main repo, because I don't have commit access to
it, and until I have done some significant testing with my commits, I
want to preserve the ability to rebase my branch.

However, now that I have some autobuilder resources to do more extensive
testing, what I'm proposing is to get my *tested* commits moved from
sgarman/denzil-next into the denzil branch after review from the
community and a merge that Richard will do.

That means the denzil branch will lag my sgarman/denzil-next branch by a
certain amount of time, which I intend to keep down to less than a week.

I can work with that. But keep in mind that if the request is not 
associated with a current bug marked for 1.2.1 in the Yocto bugzilla, I 
will need to see strong community support for including it (aka, 
multiple ACKs). This is needed to avoid scope creep in the point-release.

The more testing that's done with a pull request for 1.2.1, the more it 
can be proven that the change is low risk, and the higher chances it 
will have of making it to the final denzil branch, for certain.
