 // sockets must be the same, and in the same order (both on each socket, and
 // between sockets).

 // Currently doesn't support UDP or SSL sockets - just returns sockets that
 // synchronously fail to connect when trying to create either type of socket.
 // TODO(mmenke): Add support for both types of socket.
 // TODO(mmenke): add fuzzing for generation of valid cryptographically signed
