John, Tomas,
Thanks for looking at this, and sorry for my delayed reply. The
demands of my day job keep getting in the way. I'm feeling pretty good
about this patch though. There may still be some fine tuning to do,
but it's looking like a definite improvement over HEAD, so I'm
optimistic that I'll be able to finish it soonish.
I'll post back more detailed responses to your specific points shortly.
Regards,
Dean
