Thanks!

The import to dev7 format was done in advance. It took around 11 hours.

The *real* problem is that even the "good" figure is crap. We need
something like http://bazaar-vcs.org/DraftSpecs/FeatureBranching to
address that, making the operation take 3.2 seconds instead of 3.2 minutes.

BTW, I'm now running my benchmarks on my new desktop with an i7 920
processor and 6G of RAM. So any number which is bad on that hardware is
mega-bad on a low-to-mid end laptop. :-(
