      In our investigation of the LargeIndexedIn workload, we found a large amount of CPU cycles spent in ~PlanExecutor, specifically in ~IndexScan which deleted a large vector of OrderedIntervalList. The task of this ticket is to investigate the impact of delaying such a deallocation until after the server has written the response to the client on the wire. There may be other deallocations which can be delayed.
