            if(result.IsSuccess)
            {
                var buckets = result.Value.Where(r => r.IsSuccess).SelectMany(r => r.Value.buckets).Select(k => k.FromRiakString());
                return RiakResult<IEnumerable<string>>.Success(buckets);

Yes this might suffice. Though I do think we need to think more about it. The reason is because I think we're currently relying on the caller to enumerate the collection fully before we put the connection back in the pool. We should have a chat about how we should handle this because if they bomb out early (ie. don't enumerate the lot) then we could leak connections.
