If you're willing to change in the first palce, just put it back if it
wasn't what you expected.  From (bad) memory:

	s = signal (SIGINT, SIG_IGN);
	if (s != SIG_DFL)
		signal (SIGINT, s);

This isn't exactly worse than what you'd have done anyway, is it?
There's a very small period during which the ^C may be ignored, but I
really can't imagine it being long enough for anyone to race it, not
even expect :-)

Don't forget to put it back if it stays changed.

I hope I'm not leading you up the garden path.
