Fake login screens

Please don't think I'm just trying to stir up more noise. In discussion
with the people using this list I've seen the wisdom in taking a personal
inconvenience for the greater good regarding the C-A-B issue.
But I've tried Alt+SysRq+K on many different computer systems I have
access to. It doesn't seem to do anything. Could you please explain what I'm
doing wrong? Or help me find out if I should file a bug report?
Thanks so much.

The point was just "a way to get logged out with a keyboard shortcut" but if
you would like to still have it kill session, the kernel *does* intercept
Alt+SysRq+K as pointed out a billion times already. Seriously, we have a
userspace and a kernelspace way around this one.
