      1. Initialize a replica set with test commands enabled
      2. db.adminCommand({configureFailPoint: "failCommand", mode: "alwaysOn", data: {failCommands: ["find"], closeConnection: true}})
      3. Wait for the HMAC monitoring periodic runner to execute (or issue a shutdown, which has the same effect)
