What alternatives exist for Autologout in D7 Since the autologout module isn't ready for prime time for D7, what are some alternatives out there? 

Is there any snippet out there already that can be used in a sample custom module that will logout users for x minutes of inactivity?

Update 1: 
The suggested snippet here keeps D7 from crashing, but does not logout the user. 

Thanks!
You can just lower the cookie lifetime in your settings.php file as a temporary solution.


  Set session cookie lifetime (in seconds), i.e. the time from the session is created to the cookie expires, i.e. when the browser is expected to discard the cookie. The value 0 means "until the browser is closed.


ini_set('session.cookie_lifetime', 2000000);
