> The ServiceRecord is written twice, once when the container is initially
> registered and again in the Docker provider once the IP has been obtained for
> the container. These occur asynchronously, so the more important record (the
> one with the IP) can be overwritten by the initial record. Only one record
> needs to be written, so we can stop writing the initial record when the
> Docker provider is being used.
