So, seeing as how this is the case (verified from the Git repo for
those who are interested), I have my doubts about how relevant the
"Control X number of /'s" attack against users of the Tor network is.
 It stands to reason that of all of the /24's that make up a
particular /16, only one IP address in that entire space might be
utilized for a given circuit.  That suggests that an attacker won't
get nearly as much information with this attack as it seems.  It's
still worth noting, however.
