Ignore OOB.  Because ftpd would no longer block on sending/receiving
data, there can be a rule in cmd:
	| ABOR
		{
			if (! sending_data && ! receiving_data)
				reply(error, "no data to ABOR.");
			else {
				/* iterate over send/recv paths, close
				 * their descriptors, and free up resources
				 * associated with the connection. */
				sending_data = 0;
				receiving_data = 0;
			}
		}

It probably wouldn't work like that, but you get the idea.
