I actually don't mind adding a new primitive, and Lars says it could
be useful.  A new primitive cannot do any harm; all I'm asking is not
to start using it right away in places where we have solid code that
worked for years.  And the particular feature for which make-nonce was
intended in this case definitely doesn't need it.

However, I would like to have at least a short discussion of the
potential needs for make-nonce, and to have it in a separate thread,
so that we could be all on the same page about its need, use, and
semantics.
