>
> The following sequence of events can cause an overcommit
> --> Launch task is called for a task whose executor is already running
> --> Executor's resources are not accounted for on the master
> --> Executor exits and the event is enqueued behind launch tasks on the master
> --> Master sends the task to the slave which needs to commit for resources
> for task and the (new) executor.
> --> Master processes the executor exited event and re-offers the executor's
> resources causing an overcommit of resources.
