   @KevinYang21 Hate to say it, but this has broken the scheduler.
   
   With this dag https://gist.github.com/ashb/e429f789ed61940011d058f6dc46d4b3 the tasks downstream of print_date3 never run, even if I leave the scheduler for 30mins!
   
   ```
   select task_id, state from task_instance where execution_date='2018-01-01 00:00:00+00' order by 1;
     task_id    |   state
   --------------+-----------
    print_date1  | success
    print_date10 | scheduled
    print_date11 | scheduled
    print_date12 | scheduled
    print_date2  | success
    print_date3  | success
    print_date4  | scheduled
    print_date5  | scheduled
    print_date6  | scheduled
    print_date7  | scheduled
    print_date8  | success
    print_date9  | scheduled
   ```
