Good idea, but there is one flaw in the change. You also need to ensure
the generated random ID is unique and hasn't been used in some
considerable amount of time.. if not there will be a high risk for
conflict between two queries.

Another realted issue. Today we ignore the query component of responses.
Perhaps we should verify the response is to the correct query, not only
query id?
