We can make the prctl a single-argument thing, at the cost of not allowing \0 in the 
content. (which is probably sane anyway)

That way deployment is super-simple:

	prctl(35, "My Trace Message");
	...


	if (asprintf(&msg, "My Trace Message: %d\n", 1234) != -1) {
		prctl(35, *msg);
		free(*msg);
	}

Thanks,

	Ingo
