   * A `std::thread` cannot be copied, but can be moved. Moving a joinable
   * object transfers ownership of its thread to another object.
   *
   * A joinable `std::thread` must be explicitly joined (or detached) before
   * it is destroyed or assigned to. Attempting to destroy a joinable thread
   * will terminate the whole process.
