I think this is tricky because the random allocation of the very first tokens from the first
seed affects the choice of tokens made by the algorithm on the rest of the nodes: it basically
tries to divide the token ranges in more or less equal parts.  If your very first 8 tokens
resulted in really bad balance, you are not going to remove that imbalance by removing the
node, it would still have the lasting effect on the rest of your cluster. -- Alex
