> (commented this on ZOOKEEPER-338)
> I've just noticed that we call getaddrinfo from zookeeper_interest... on
> every call. So from zookeeper_interest we always call update_addrs:
> https://github.com/apache/zookeeper/blob/trunk/src/c/src/zookeeper.c#L2082
> which in turns unconditionally calls resolve_hosts:
> https://github.com/apache/zookeeper/blob/trunk/src/c/src/zookeeper.c#L787
> which does the unconditional calls to getaddrinfo:
> https://github.com/apache/zookeeper/blob/trunk/src/c/src/zookeeper.c#L648
> We should fix this since it'll make 3.5.0 slower for people relying on DNS. I
> think this is happened as part of ZOOKEEPER-107 in which the list of servers
> can be updated.
