Normally, if the user use the CTRL+C keys, the Eiffel application detect it as an error and throw an exception of type <code>{OPERATING_SYSTEM_SIGNAL_FAILURE}</code>. To manage the CTRL+C keys, you can use a <code>rescue</code> clause to detect the exception and a <code>retry</code> mecanism to cancel the exception handeling done by the Eiffel runtime.
