Nope, that doesn't work on the Sage repo. Exporting all 9028
changesets of 2.11.alpha1 took about 40 minutes, but on reimport to a
fresh repo failed around 1300 changesets. The problem is that export
of a merge on diffs against on parent. So if you resolve a merge
conflict in a merge changeset things go FUBAR.

That was with 0.9.5, but I haven't tried 1.0 yet.
