BTW, I assume one doesn't need any synchronization for things like
cancellation flags etc., right?  I.e. main thread could just

        ...
        child_thread->cancellation_flag = 1;
        ...

and the child thread could just

        while (!thread->cancellation_flag && !thread->job_done) {
          ...
        }

?
