      Change /etc/resolv.conf to new nameserver. Shutdown old nameserver. Wait for getaddrinfo() resolution failures.

      Description

      Updating /etc/resolv.conf will have no effect on running mongod instances until they are restarted due to nameserver caching in glibc.

      According to Ulrich, calling res_init() will cause this to happen.
