    Description

      This is a follow-up task for TEZ-4234 (TEZ-4135). Let me quote jeagles here:
      "I think we may find more add-ons to this feature that will continue to gain performance. Perhaps rounding the allocation to (say 8bytes -> 64bits) or setting a minimum on buffer size or finding a more reasonable growth pattern to encourage reuse."
