> At the moment, all {{AbstractStreamOperator}} register their {{Closeables}} at the containing {{StreamTask's}} {{CloseableRegistry}}. In order to separate the closing of stream operator specific {{Closeables}} it might make sense to instantiate a {{CloseableRegistry}} for each {{AbstractStreamOperator}} and registering this registry at the {{StreamTask's}} registry. That way the {{AbstractStreamOperator}} can close it's own {{Closeables}} without affecting other {{AbstractStreamOperators}} and not having to wait for the {{StreamTask}} to close by closing its own {{CloseableRegistry}}.
