I like this approach, but this requires storing the rest of the enumeration. I think that you would want to the continuation token to expire after a reasonable period of time (10 minutes to 1 hour). When the token expired, you would remove the rest of the enumeration from your data store.
This isn't what the author recommends, but I think this is a good approach.
