Hello fellow ZooKeepers,

We have now had three separate production incidents where one of the root 
causes was flaky DNS causes the ZooKeeper C client library to completely crash.

This has been a known bug since at least 2011, 
https://issues.apache.org/jira/browse/ZOOKEEPER-1029

I'm having trouble defending to my colleagues how ZooKeeper, which is so 
integral to building reliable software, can have such a serious issue go 
unanswered for 4 years.  What needs to be done to get this issue some developer 
love?

Thanks,
Steven
