> When an operator uses the {{machine/down}} endpoint, the master sends a shutdown message to the agent.
> We need to discuss and resolve the semantics that we want regarding the operators and frameworks knowing when their tasks are terminated.
> One option is to explicitly remove the agent from the master which will send the {{TASK_LOST}} updates and {{SlaveLostMessage}} directly from the master. The concern around this is that during a network partition, or if the agent was down at the time, that these tasks could still be running.
> This is a general problem related to task life-times being dissociated with that life-time of the agent.
