Nice thought.
Actually, this or something like this might be helpful in maintainting
invariants in the face of exceptions.
Though this is a tough problem especially in the face of threads.
Though versioned variables may be able to remove most of the locking
issues and move it down into the commit phase.
(But as always work is conserved. Somebody has to do the dirty work.)
