No, for a single user of a single tenant the CarbonContext can be created just once. The reason is, our authorizations are based on user, and we create separate instances of registries, which are user-aware so that the credentials can be provided only once. This is because we don't have a concept of credential which is cached at the Context-level. If we have that, we don't need multiple registry and realm objects. The same should also solve multiple similar problems. However, I'm not sure about the impact this change would bring. WDYT?
