Tested this with 1000 concurrent users and we're doing really well on cache

> [~gopalv] 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.
