Since upgrading to Lion have you noticed a new option on your login screen? I believe that when I installed Lion (or the iCloud update) Apple enabled a new feature which allows a user to restart the machine into a special guest mode, which features Safari only. What's particularly interesting is that when a user is logged in and the screen is locked a guest user can terminate the user's session to do this. Granted the same could probably be accomplished by holding down the power button, but still concerning.
Not sure if I'm right about the origin of this feature, but irregardless I finally figured out that you could disable it via System Preferences -> Security & Privacy -> General tab. If this feature is still enabled on your Mac you may want to take a look into it. If anyone knows more specifically when this was introduced I would appreciate you letting me know. Enjoy the last bit of your weekend!
