The caching is done on top of WPDB, not through it.

Also, what about DML queries? (INSERT, DELETE etc.)

    initial v1  
    11wpdb::get_row never uses the cached results, look at this
    22
     3{{{
    34        function get_row( $query = null, $output = OBJECT, $y = 0 ) {
    45                $this->func_call = "\$db->get_row(\"$query\",$output,$y)";
    … …  
    89                        return null;
    910                // more code
     11}}}
    1012
    1113and then
    1214
     15{{{
    1316        function query( $query ) {
    1417                if ( ! $this->ready )
    … …  
    2124                $return_val = 0;
    2225                $this->flush();
    23 
     26}}}

    2528See 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.
