> There is a bug in the current implementation of hostdb's use of hostsfiles. Because it uses a static local variable the storage is shared and ultimately will lead to race conditions if the hosts file is reloaded.
> {code}
> if (find_result != current_host_file_map->hosts_file_map.end()) {
>     // TODO: Something to make this not local :/
>     static HostDBInfo r;
>     r.round_robin = false;
>     r.round_robin_elt = false;
>     r.reverse_dns = false;
>     r.is_srv = false;
>     ats_ip_set(r.ip(), (*find_result).second);
>     return &r;
>   }
> {code}
