> in LOST tasks.

> Project: Aurora
> Issue Type: Bug
> Components: Executor
> Reporter: brian wickman

> Originally filed by [~bmahler]
> Currently, it appears as though Thermos will attempt to send status updates
> while the slave is down. This is correct, as the executor driver will re-send
> unacknowledged updates when the slave reconnects.
> However, since Thermos does not wait for re-registered(), it's possible for
> Thermos to exit before the slave reconnects and the driver flushes
> unacknowledged updates.
> To ensure updates are sent to the slave, Thermos must wait for reregistered()
> before exiting, if disconnected() was called. That is, in between
> disconnected() and re-registered(), Thermos must not send status updates and
> exit if reliable status updates are desired.
