Google for "AllowClosedownGrabs" and "AllowDeactivateGrabs". And they have been removed for good reason: If you could kill an application holding a grab merely by hitting a special hotkey, this will give you a easy to use, builtin Xscreensaver lock circumvention mechanism. Grabbing the input devices may be used as an vector of attack on a system, but it also serves as an important security mechanism.
