How about the code in osiop.c?

		int timeout = acb->xs->timeout;
		/* start expire timer */
		timeout = (timeout > 100000) ?
		    timeout / 1000 * hz : timeout * hz / 1000;
		if (timeout == 0)
			timeout = 1;
		callout_reset(&xs->xs_callout, timeout,
		    osiop_timeout, acb);

I'm not sure which is better to use u_int64_t or conditional, though..
