-----------------------------------------

A related issue is the early exit for the case where the framework is not connected, https://github.com/apache/mesos/blob/f1789b0fe5cad221b79a0bc2adfe2036cce6f33d/src/slave/slave.cpp#L5803-L5810.

> When the following steps occur:
> 1) A graceful shutdown is initiated on the agent (i.e. SIGUSR1 or /master/machine/down).
> 2) The executor is sent a kill, and the agent counts down on executor_shutdown_grace_period.
> 3) The executor exits, before all terminal status updates reach the agent. This is more likely if executor_shutdown_grace_period passes.
> This results in a completed executor, with non-terminal tasks (according to status updates).
> This would produce a confusing report where completed tasks are still TASK_RUNNING.
