This is a cluster which is horribly imbalanced because I didn't assign
initial tokens, so I'm adding 6 nodes with tokens according to the operations
page (ie, i * (2^127/N) with N = 6).
So here's what the ring will look like when bootstrap finishes

Old 1 673.76 GB 1620761242680682425026573496599110901

So from this it seems like I should see anti-compacition on old nodes
4, 5, 6 and 1.
Looking now, it seem that 1 and 6 have had some anti-compaction
happen, node 4 has
INFO [STREAM-STAGE:1] 2010-07-14 20:53:26,579 StreamOut.java (line 95)
Performing anticompaction ...
in the log but not a corresponding
CompactionManager.java (line 339) AntiCompacting [..]
line
Node 5 has nothing in its logs about anti-compaction.
Is the fact that 2 new nodes are in the range messing it up? And if so
how do I recover (I'm thinking, shutdown new nodes 2,3,4,5, the bringing
up nodes 2,4, waiting for them to finish, then bringing up 3,5?).
