I suppose this computation is being repeated by each esp. Is there a way by
which it can done once and shared (say computed during fixup)? If possible,
this would be a minor enhancement for later. I do see some comment indicating
that only portions relevant to this esp are computed. Maybe some comment
including a statement on which locality_balance_level this corresponds to will
help.
