      Description

      From the cassandra user message board:
      "I just recently upgraded to latest in 0.5 branch, and I am running
      into a serious issue. I have a cluster with 4 nodes, rackunaware
      strategy, and using my own tokens distributed evenly over the hash
      space. I am writing/reading equally to them at an equal rate of about
      230 reads/writes per second(and cfstats shows that). The first 3 nodes
      are seeds, the last one isn't. When I start all the nodes together at
      the same time, they all receive equal amounts of reads/writes (about
      230).
      When I bring node 4 down and bring it back up again, node 4's load
      fluctuates between the 230 it used to get to sometimes no traffic at
      all. The other 3 still have the same amount of traffic. And no errors
      what so ever seen in logs. "
