Comment (by eschnett):

 Instead of moving parallelization to a lower level, it would probably be
 more efficient to move it even higher up. For example, given a single
 refined region on a single MPI process, its six boundaries should be
 prolongated in parallel. Doing this efficiently and dynamically requires
 an infrastructure that is more flexible than a typical OpenMP
 implementation.

 In the short term, using LoopControl (where applicable) in the
 prolongation operators' loops is probably the best, as you suggest.
