It took about 50 minutes for bzr to download 281 MB, then, as reported above, it appeared to stall for more than 10 minutes, but the bzr process continued to consume 80-90% CPU. (This is with an Athlon XP 2100+ (1.7 GHz) and 2 GB RAM over a rather slow wireless connection.) Just as I was about to kill it, it finished. I then made a quickfixes branch from the (now local) trunk, which took only about 10 seconds, and bootstrapped from the quickfixes branch without a problem. Steve Berman
