Wow - this question generated lots of replies! I'm still reading through all
of them.

I have another idea, but not sure if this will work:

def RemoveDupsFromLists ( list1 , list2 )
    list1.each_item do | i |
        list2.each_item do | j |
            if !(list2[j].nil?) and list1[i] == list2[j]
                list1[i] = nil
                list2[j] = nil
            end
        end
    end
    list1.compact!
    list2.compact!
    return [ list1 , list2 ]
end
