$ time bzr annotate builtins.py > /dev/null

real    0m1.479s
user    0m1.430s
sys     0m0.030s

builtins.py has 953 ancestor revisions (i.e. revisions that modified it)
and 3016 lines.

That's on a machine with 4141.87 Bogomips.  I did optimize annotate
slightly, but I'm submitting the optimization for our 0.14.0 release.
