Hi, all!
I am trying to make init program on picolisp (yes, I am that crazy).
When Ctrl+Alt+Del is pressed, SIGTERM is sended to init process,
so I want to handle this signal.
I made patch which add new global *Term.
When it is defined and retures non-NIL, standard handler is not processed.
I think it is good idea to have such handler.
Regards, Constantine
