 Quite the speed improvement!

 And here's an easier to read (IMO) of the example:

 {{{
 $query = new WP_Query( array(
         'meta_query' => array(
                 array(
                         'key' => 'foo'
                 ),
                 array(
                         'key' => 'bar',
                         'value' => 'val2'
                 ),
                 array(
                         'key' => 'baz'
                 ),
                 array(
                         'key' => 'froo'
                 ),
                 'relation' => 'OR',
         ),
 ) );
 }}}
