You can't just rely on session.gc_maxlifetime because after this time the session is marked as garbage and the garbage collector starts only with a probability of 1% by default ( session.gc_probability).

The better approach IMHO is to handle yourserlf the expired data.

You can for instance start the time and save it into a session variable:

Later..via cron you can do something like this:

 $timeout){//Session is expired
  //delete file
  session_destroy();
}else if (!isset($_SESSION['last_seen')){ //already garbaged
  //delete  file
  session_destroy();
}
?>

Not tested...just an idea
