NACK.

So I don't remember why I wrote this code, but I don't think I was 
expecting it to be 2ms.  Instead, I think I just wanted it to be some 
delay, but I believed that schedule_timeout(1) was too short or would be 
"optimized" out somehow.

Note that right below this, I do:

	if (qe_port->wait_closing) {
		/* Wait a bit longer */
		set_current_state(TASK_UNINTERRUPTIBLE);
		schedule_timeout(qe_port->wait_closing);
	}

And wait_closing is a number of jiffies, so I knew that 
schedule_timeout() took jiffies as a parameter.

So I think I'm going to NACK this patch, since I believe I knew what I 
was doing when I wrote it five years ago.
