Re: Major update just committed

    During the debugging phase people should just refrain from any "major work"
    which would distract them from debugging.  When this "refraining" because
    too difficult, it's a sign that there isn't enough debugging to do any more,
    so it's a good time to branch.

That seems like a good standard.  However, we could still install
new versions of self-contained packages such as Gnus.
