Step 4: Release the Association

The process closes the association until it receives the positive release

response from Process B.

Process A monitors events with ap_poll() and receives the response by

calling ap_rcv().

If an association is released abnormally, for example, if a lower layer

problem occurs, a provider abort (A_PABORT_IND primitive) may be

received.
