           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2

UniqueVector is very expensive: its cost is the sum of the cost of maintaining both the map and vector, it 
has high complexity, high constant factors, and produces a lot of malloc traffic.  It should be avoided.
