       * don't send describe if we already have cached the row description from previous executions

       * XXX Clearing the fields / unpreparing the query (in sendParse) is incorrect, see bug #267.
       * We might clear the cached fields in a later execution of this query if the bind parameter
       * types change, but we're assuming here that they'll still be valid when we come to process
       * the results of this query, so we don't send a new describe here. We re-describe after the
       * fields are cleared, but the result of that gets processed after processing the results from
       * earlier executions that we didn't describe because we didn't think we had to.
       *
       * To work around this, force a Describe at each execution in batches where this can be a
       * problem. It won't cause more round trips so the performance impact is low, and it'll ensure
