Review comment:
@pgandhi999 I don't follow your explanation -- I think I agree w/ @Ngone51 .
yes, TSM calls `DAGs.taskEnded` while it has a lock on the TaskSchedulerImpl,
but the `DAGs.taskEnded` call just puts an event into the queue and then
returns. So this part is happening w/ out the lock. but maybe you meant
something else?
