 Replying to [comment:15 nickm]:
 > I've added some comments and questions to the branch on github. Let's
 discuss more there.  Thanks, Isis!

 Replied to the comments on
 https://github.com/isislovecruft/tor/commit/5a984badc59927063d9682ffd8cc6f52fc15a44b
 and made a bunch of fixup commits ([https://travis-
 ci.org/isislovecruft/tor/builds/369360848 Travis fails] because we need to
 pull in the appropriate tor-rust-dependencies changes). A squashed version
 is in my `bug24660_r1`
 [https://gitweb.torproject.org/user/isis/tor.git/log/?h=bug24660_r1
 branch].

 The requisite tor-rust-dependencies changes are in my `add/rand_core`
 [https://github.com/isislovecruft/tor-rust-dependencies/tree/add/rand_core
 branch] and `add/rand` [https://github.com/isislovecruft/tor-rust-
 dependencies/tree/add/rand branch].
