   DESCRIPTION
   io_setup  creates  an asynchronous I/O context capable of receiving at
   least nr_events.  ctxp must not point to an AIO context  that  already
   exists, and must be initialized to 0 prior to the call.  On successful
   creation of the AIO context, *ctxp is filled  in  with  the  resulting
   handle.
