ZOOKEEPER-702

[Flavio Junqueira]

Hi, ZOOKEEPER-702 changes the way we do failure detection in  
ZooKeeper, and it is an important change. I'd like to see it committed  
soon (it has been sitting there for a while), but at the same time I'd  
like to make sure that no one has an issue with it. If this is  
interesting to you or affects you in any way, please consider having a  
look at it soon.

Thanks,
-Flavio
