Like Diffbench, but bigger and better.  Diffbench looks like it does a
quick comparison of two states of the project.  That's something this
can do, but my vision for it is to build a database of benchmark results
for multiple machines and for commits going back as far as we can figure
out how to build and run them, so we can see how performance has changed
over time and how it varies on different systems.
