Update.

	* rt/tst-aio.c: Add test for aio_read and lio_listio.

	* rt/lio_listio.c: Correct total counter handling.

	* rt/aio_misc.c (handle_fildes_io): Correctly dequeue elements
	from request queue.

	* test-skeleton.c (main): Make stdout unbuffered.  Improve message
	of signal on exit even more.
