This is because initially, only 20 descriptors are allocated, and
the system is quietly ignoring any descriptors over the allocated
amount:
if (uap->nd > p->p_fd->fd_nfiles)
uap->nd = p->p_fd->fd_nfiles; /* forgiving; slightly wrong */
This should be:
if (uap->nd > p->p_fd->fd_nfiles)
return (EBADF);
