Inherited methods
Shuts down the stage, deallocating resources, etc.
Shuts down the stage, deallocating resources, etc.
It will be called when the stage receives a Disconnected
command unless inboundCommand is overridden. This method
should not send or Disconnected
commands.
It is possible that this will not be called due to failure of other stages to propagate shutdown commands. Conversely, it is also possible for this to be called more than once due to the reception of multiple shutdown commands. It is therefore recommended that the method be idempotent.

This method should not effect other stages by sending commands etc unless it creates them.
It is not impossible that the stage will receive other commands besides Connected
before this method is called. It is not impossible for this method to be called multiple
times by misbehaving stages. It is therefore recommended that the method be idempotent.
