Which excludes using system() - the only "ANSI C" way to spawn a
child AFAIK. One would expect system() to take care of setting
the child's handler to default, if there were something like an
implied guarantee that a program starts with default signal settings.
Yes, a program using system() could bracket all calls of system() with
set-signal-to-default / set-signal-to-ignore, but that temporarily
changes the parent's handler which may or not be acceptable.
