I wonder if for at least Linux host the driver shouldn't attempt to increase
stack size for its children, say to 32MB if possible:

{
  struct rlimit rl;
  if (getrlimit (RLIMIT_STACK, &rl) == 0)
    {
      if (rl.rlim_cur != RLIM_INFINITY
          && rl.rlim_cur < 32*1024*1024
          && (rl.rlim_max == RLIM_INFINITY
              || rl.rlim_max > rl.rlim_cur))
        {
          if (rl.rlim_max == RLIM_INFINITY || rl.rlim_max >= 32*1024*1024)
            rl.rlim_cur = 32*1024*1024;
          else
            rl.rlim_cur = rl.rlim_max;
          setrlimit (RLIMIT_STACK, &rl);
        }
    }
}

then I guess maximum tinst depth could go back to 1024.
