session_disconnect()

I am working on some AJAX callbacks. These need to open the session, get hold of stuff in $_SESSION and that is it ... they won't be changing the session data. The trouble is that because the session file is locked the Asynchronicity of AJAX is reduced a bit, especially if some of the server side calls need a lot of work. May I suggest: session_disconnect(); This would, in effect, close the session file but leave $_SESSION. This would be easy to implement, just call the second callback to session_set_save_handler(). This is NOT quite the same as a session_end() function since that would presumably write the (changed) contents of $_SESSION back to where ever. With session_disconnect() any changes made to $_SESSION would be lost regardless of them being made before or after the call to session_disconnect(). Another way of doing this would be to add an optional boolean argument to session_start() which would load $_SESSION and then disconnect. This is more intrusive in that changes to any user open functions (of session_set_save_handler()) would be needed. It might be a tiny bit faster or neater. I do not know how much of a speed improvement this would make to what sort of AJAX applications.
