input_server addon (which isn't done), you have to kill the process manually. Does not do password validation. Does not stop you from jumping to another workspace to kill the SS (which would allow you to circumvent password protection). git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6937 a95241bf-73f2-0310-859d-f6bbb57e9c96
