Trouble with instantiating another WP_Query is that filters and
actions have NO way to know on which wp_query object they are working
on.
What if I need some filtering on one custom wp_query object, but none
on the main wp_query loop ?
The filter has to work depending on current query_vars... but how
could it know them ? (global $wp_query;
print_r($wp_query->query_vars); will work on the main wp_query, but
not on the custom one)

Possible solutions :
adding an optional query_var "name"  to each wp_query object
