So, given the existing implementation does not lend it self well to large-scale (read: large unsolved lists) processing, and the current leaning away from tightly-coupled multiprocessing, is my approach something the John developers are interested in?

I can certainly pull bits of my code into John, integrate it, and give you something to try.  I continue to suggest, however, that moving to a threaded mode, rather than fork, would be a far better performance overall.
