 wpdb::get_row never uses the cached results, look at this

         function get_row( $query = null, $output = OBJECT, $y = 0 ) {
                 $this->func_call = "\$db->get_row(\"$query\",$output,$y)";
                 if ( $query )
                         $this->query( $query );
                 else
                         return null;
                 // more code

 and then

         function query( $query ) {
                 if ( ! $this->ready )
                         return false;

                 // some queries are made before the plugins have been
 loaded, and thus cannot be filtered with this method
                 if ( function_exists( 'apply_filters' ) )
                         $query = apply_filters( 'query', $query );

                 $return_val = 0;
                 $this->flush();


 See how the cache never gets called? if you write a query, the old one
 gets flushed without checking if it was the same as before, if you use
 null, null gets returned, an if($this->last_query != $query) needs to be
 put in ::query or the return null removed from ::get_row, I'd prefer the
 first solution.
