 > Your branch bug10758 looks good.  I tweaked it a bit in my force-updated
 bug10758 branch.

 Looks okay to me.

 > I also ran my bug10758 branch in a Shadow network with 20 relays which
 worked without obvious issues.

 Okay.  That's not likely to turn up all possible errors, since any weird
 stuff that breaks is going to break because of:
    * Older versions of Tor
    * Nodes what not all authorities find out about
    * Directories going up and down
    * Other stuff

 But it's better than no testing at all.

 > With respect to nodelist.c and routerlist.c, I'm not really sure which
 functionality you'd want to keep.  Can you be more specific, e.g., which
 functions would you want to reimplement for v3?

 Well, I'm mostly hoping for a review of all the complex pieces and subtle
 little lines there to make sure they didn't do something crucial that
 wasn't related to the v2 networkstatus system.

 Here are some examples:
    * v2_ns_dl_status didn't have some extra unexpected meaning, did it?
    * Did anything bad just happen to routerlist_remove_old_routers?

 I think the answers are "no", but that was some complex logic I just
 chopped out.
