Cool - I'd not seen that. One question - the page you reference
suggests that a shallow branch will take "roughly as long as a
lightweight checkout would take". When I tried a lightweight checkout
of the Python tree, it still took 11 minutes, vs 3 minutes for svn co.
Is this due to architectural differences, or is this just a fixable
performance difference, and I should expect that in the longer term,
bazaar lightweight checkouts will get closer to svn co in performance
