Update.
2000-08-11  Ulrich Drepper  <drepper@redhat.com>

	* rt/aio_cancel.c: If canceling a specific request which is running
	*really* do nothing.
	* rt/aio_misc.h: Add `done' to states of a request.
	* rt/aio_misc.c: Add several tests for the correct state.
	Simplify request table memory handling.
