Fix the damn code then, I'm just a docs committer (in theory).  And the code
certainly does seem to do this, check in_pcb.c:


	if (first > last) {
		/*
		 * counting down
		 */
		count = first - last;

		do {
			if (count-- < 0) {      /* completely used? */
				/*
				 * Undo any address bind that may have
				 * occurred above.
				 */
				inp->inp_laddr.s_addr = INADDR_ANY;
				return (EAGAIN);
			}

			...

What *should* it return?
