zdelta seems to be a research project. It does compress better than the xdiff
lib, but the speed improvements against xdiff(1) are probably because the
resulting tree is smaller. I favor the xdiff code because it's so much
smaller, and seems easier for us to maintain.
For performance, there's still quite a bit of tuning that can be done in terms
of when and how we delta.
