Fwd: Is disabling ctrl-alt-backspace really such a good idea? - no.

Every program that hangs but doesn't release grabs is a problem. You
could certainly implement some kind of solution to that, but only
after that solution is implemented, C-A-B or equivalents should be
disabled. Not before.

Every program that makes the system so slow that it becomes unusable
is a problem. This can't be solved. Any buggy program can take so much
CPU/RAM/IO that your mouse pointer moves only every 10 seconds and
your key presses only register after that same time. Only a simple key
press that kills the program can solve this. Or a hard reset. We
shouldn't remove the reset button functionality either.

This means that C-A-B or equivalents can never be disabled.

Concrete examples: Windows games run in Wine. Some will leak memory or
whatever. You can't file bug reports against those games. And even if
you could, you would still experience the problem until it was solved.
