> In order to help improve usage tracking, allocations for a single query should all roll up to a single root.
> This requires that the Foreman create that root, and label it, and then pass that along to anyone else that needs to create additional sub-allocators. The patch for DRILL-2406 introduces the creation of a new allocator in QueryContext, but this is currently a child of the Drillbit's TopLevelAllocator, violating the principle above. This is a reminder to fix that after the dependencies above are available.
> As well as the known case in QueryContext, check to make sure other locations aren't creating new children from the DrillbitContext, but are instead using the allocator from the FragmentContext instead.
