Re: [infinispan-dev] https://issues.jboss.org/browse/ISPN-977

With the new push-based rebalancing code, we install the new CH before doing any rebalancing work, so the inconsistency window should be much smaller. In theory we also block new transactions, maybe you could use that to stop generating new keys while rehashing.

On the other hand, in 5.0 you should be able to implement KeyAffinityService on top of Pete's grouping work for https://issues.jboss.org/browse/ISPN-312 and then you won't need any listeners.
