Handle 'Zap' - Ctrl-Alt-Backspace more gracefully
|
|
|
|
To avoid accidental zapping of the Xserver warn after
|
|
the first ctrl-alt-backspace by emitting a beep. Only
|
|
Zap the server if a second ctrl-alt-backspace is sent
|
|
within 2 seconds.
|
|
This can be enabled with a new option flag "ZapWarning"
