Comment(by mikeperry):

 Ok I reviewed the patch. It looks OK to me, modulo a couple remaining
 concerns. So, here's the action items for mike:

 1. Add back in calls to entry_guards_changed() from my branch
 2. Set a flag on cannibalized circuits and check it to avoid double-
 counting
 3. Run the thing for a little while
 4. Solve those two math problems if I can, or at least stochasticcally
 estimate them in a python snippet

 Then after that, we can do the doc updates. We probably want the math
 before the docs, if we can manage it.
