+
+ The "subtasks" field also contains a 'status' key, that contains a dict that stores status
+ information for each subtask. At the moment, the value for each subtask (keyed by its task_id)
+ is the value of `status`, which is initialized here to QUEUING.
+
+ This information needs to be set up in the InstructorTask before any of the subtasks start
+ running. If not, there is a chance that the subtasks could complete before the parent task
+ is done creating subtasks. Doing so also simplifies the save() here, as it avoids the need
+ for locking.
