When a program that does this +misbehaves or become unresponsive, you cannot do +anything but manage it from another computer or +restart the computer.

Thus, +unless a client breaks this rule, you can always +have your server for switching to the TTY at a +higher priority than other programs. + +A similar, and probably related, problem in X.org +is that global keybindings don't work when a +popup or menu has focus.
