      Description

      Gopal Vijayaraghavan found issues when running lots of concurrent queries against HS2 with the query cache. Looks like the FetchWork held by the results cache cannot be shared between multiple queries because it contains a ListSinkOperator that is used to hold the results of a fetch.
