Agree this is a bit confusing. What I'm sure about is that, 
computeResourceProfile() is the last place spool query option can be disabled. 
So I believe, as long as queryOptions.setSpool_query_results(false) is called 
before calling PlanRootSink constructor, we will be fine.

Now that we discuss this, I realized that the spool option check in 
computeProcessingCost() might be too premature because it can be disabled in 
computeResourceProfile() later (computeProcessingCost calls preceed 
computeResourceProfile). I can take a look at them separately.
