lukem e9aa053c09 Add raise_default_signal(3) -- raise the default signal handler.
Can be used by applications that have their own SIGINT (et al)
handlers and want to exit in a manner that correctly
signals to the parent that the process was terminated by a signal.
See http://www.cons.org/cracauer/sigint.html for more info.
