Is there a real alternative on the Mac to Ctrl+Alt+Delete (not the "force quit" dialog)? Are there any real alternatives to force quit dialog on mac?

Alternative, just a command/app that kills every running app (not process)?
Found how to accomplish what i want:


Create spark applescript command doing do shell script "sudo killall
loginwindow"
Edit /etc/sudoers to allow doing above without password
prompt: Tyilo ALL=NOPASSWD:/usr/bin/killall
