   How does this handle fan-out style parallelism.  For example, you can generally filter batch N while filtering batch N+1 at the same time.  Would there be a single ExecNode that is run twice?  If so won't you have trouble tracking inputs?  Or would there be two ExecNode instances in the plan?  In that case how would you decide which node to deliver batches to?
