This would be my preference.  The solution in your patch set has a lot
of duplicate code with different per application scalars.  I would think
that an abstract class would be a more elegant design.  I OK with
pushing your current patches and refactoring the scalar code into an
abstract class at a later date.  I don't have a strong preference for
singleton versus static.

This should be the goal.  My guess is there are lots of
inter-dependencies that will make this goal more challenging then you
might expect.  I looked at this a long time ago and that was the
conclusion that I came to.  Maybe over the years, some of that ugliness
has been refactored away.
