Wow, that's impressive! How long does a "git gc --agressive" run take?

That could be because of the duplicated history we had there in
December, that I then fixed. I reset the branches to just before the
screwup, and then ran fromcvs to catch up with CVS HEAD again. That
duplicated history is probably still there, but nor reachable from any
branches or tags.

Should we run "git prune" to get rid of the garbage?
