Review comment:
StreamThread#updateThreadMetadata does not actually update the map what
it does is link a object reference to the map in the Task to the TaskMetadata.
This makes it so that whenever the TaskMetadata is fetched it has the most up
to date maps. For that to matter we need to update the map more frequently
