    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
