Multiple execution emulation fails as in the following script: 
  $db  = DB::connect("mysql://localhost/test");
  $some_query_with_params = "DELETE FROM TST WHERE id = ? ";
  $params = array(1,2,3);
  $stmt = $db->prepare($some_query_with_params); 
  foreach($params as $param)
    $db->execute($stmt, array($param)); //Fails !!!

The reason for that is executeEmulateQuery() code:

    function executeEmulateQuery($stmt, $data = false)
        $p = &$this->prepare_tokens;
        $stmt = (int)$this->prepare_maxstmt++; // BUG ?

        if (!isset($this->prepare_tokens[$stmt]) ||
            !is_array($this->prepare_tokens[$stmt]) ||
            !sizeof($this->prepare_tokens[$stmt])) {
            return $this->raiseError(DB_ERROR_INVALID);

        $qq = &$this->prepare_tokens[$stmt];
        // and so on...
What does the second line do?:
  $stmt = (int)$this->prepare_maxstmt++;
It ignores the input parameter $stmt, sets it to some unreasonable value, and we 
always get DB_ERROR_INVALID. If the line is removed - everything works. Apparently 
this line should not be here at all.
