If I understand you correctly, I agree: the
"stable"/"testing"/"unstable" is just a simplification of the actual
process, used to help clarify things to the general public and QA.  In
actual practice, there is also a separate staging area used to test
"updates to a released stable build".  Renaming 'testing' to 'stable'
happens atomically when we do a release.  Updates to the stable build
after that happen on a special testing branch which is separate from
the "testing"/"unstable" branches on which the next release is being
formed.

If we use 'dist-olpc8.1', 'dist-olpc8.2', etc branches in koji, then
having 'dist-olpc8.1-testing' and 'dist-olpc8.2-testing' branches
makes sense.  For most cases, if 'dist-8.1' is stable then 'dist-8.2'
is testing and 'dist-8.2-testing' is unstable, but preparation of an
8.1.1 may happen on 'dist-8.1-testing' if packages can't be pulled
directly from 'dist-8.2'.
