      Description

      ExchangeHistory keeps a FinishState for every topology version.
      FinishState contains msg, which contains at least two huge maps:
      partCntrs2 and partsSizesBytes.

      We should probably strip msg, removing those two data structures before putting msg in exchFuts linked list to be stowed away.
