>
> Currently, we only reply to a reconciliation request when the task state
> differs. This makes it difficult for a framework to implement reconciliation:
> if the framework does not receive an update for the task, it cannot determine
> if this was because the state is valid, or the slave was transitioning, or
> the master has not recovered yet.
> As a consequence of this, frameworks looking to reconcile tasks need to
> continually retry at small intervals to compensate for the lack of ability to
> differentiate the cases listed above.
> A solution to this problem is to send an update for all of the tasks, if
> possible. This means we no longer compare task states to determine when to
> send an update.
