> This was discovered when simulating frequent slave restarts on a staging cluster.
> It appears that when we reconcile tasks from a re-registering slave, we correctly remove the task and update the slave's {{resourcesInUse}}. However, there can be an executor associated with this task, and the reconciliation currently does not do anything to reconcile the executor's resources.
> We'll need to ensure the reconciliation properly removes executors corresponding to these lost tasks.
