Not a bad idea. Like this?

	if (setjmp (&context)) {
		struct pseudo_object X __attribute__((cleanup(pdtor)));
		X.normal_termination = 0;
		X.ctx = &context;
		/* ... */
		X.normal_termination = 1;
	} else {
	}

And pdtor() will either just return or longjmp to ctx depending
on normal_termination.

There's still a minor cost but I guess it's ok.

Thanks,
