  Haven't done it myself but my guess is that your failure to Remove the
initial request is causing the problems.  I suggest trying the same code
used for aborting and removing an asynchronous printer request:

/* ior is your pointer to your console read IORequest */

if(!(CheckIO(ior))
   {
   AbortIO(ior);
   }
WaitIO(ior);  /* Removes the request */
