I'm concerned with the change (and don't think it should happen at this point, as I want to be able to tell other people their changes are too big). It's probably not another O(p) structure, since a process will have to know the other rank's disp_unit to do the memcpy during the communication operations, so we crossed the O(p) bridge when we added disp_unit to allocate_shared.
