[infinispan-dev] New events to reflect topology change Was: https://issues.jboss.org/browse/ISPN-977

First thing I thought when reading your email was "OMG do we support on-the-fly hash implementation changes? crazy!" That's obviously not the case, but if you name it as @ConsistenHashChangeListene that's what I would think. Wouldn't it be better to change the exact timing of the viewchange event? I don't see why Infinispan users might be more interested in knowing about the topology details according to the transport than what they are about the actual Infinispan hashing topology - I would expect that when I receive which notification the new view is already installed and ready to go; actually I thought that was the case since ever. What would be the use cases to get the notification *before* the new hash is installed?
