Duplicated Queries if call rdf_query [#1320004]

Hi,
every time i call rdf_query(....)
the rdf_get_repositories is called more than one times.
look at function _rdf_get_callbacks(), file rdf.api.inc

then i have several sql queries like "SELECT COUNT(did) FROM rdf_data" or "SELECT COUNT(did) FROM rdf_data_file"

i think its enough to build one repositories array per page load

i want to set the repository in my modul with some simple code like that

        // if rdf_repository es empty load it
        if(empty($GLOBALS['rdf_repository'])){
		$repos = rdf_get_repositories();
		rdf_use_repository($repos);
	}else{
                //else reload from global
		$repos = $GLOBALS['rdf_repository'];
	}
         // call rdf_query with my $repos
        $data = rdf_query(NULL, rdf_qname_to_uri('dc:source'), $file->uri, $repos['my_repos']);

to work this way if removed the line

$repos = !empty($repos) ? array_intersect_key(rdf_get_repositories(), array_flip($repos)) : rdf_get_repositories();

in function _rdf_get_callbacks, file rdf.api.inc

i know that this solution can have site effects when rdf_get_repositories() is never called before.
so function _rdf_get_callbacks needs more work

something like that???

function _rdf_get_callbacks($op, $rdfrepos = NULL) {

  $callbacks = array();
  if(empty($GLOBALS['rdf_repository'])){
    $repos = rdf_get_repositories();
    rdf_use_repository($repos);
  }else{
    $repos = $GLOBALS['rdf_repository'];
  }
  if(!empty($rdfrepos) && $repos[$rdfrepos]){
    $repos = array($rdfrepos => $repos[$rdfrepos]);
  }

  foreach ($repos as $repo) {
    ........
