10 * Bug fix: memory used by GRS records wasn't freed.
11 * Rewrote some of the error handling code - the connection is always
12 * closed before failback is called.
13 * If failback is defined the send APDU methods (init, search, ...) will
14 * return OK but invoke failback (as is the case if the write operation
16 * Bug fix: ref_count in assoc object could grow if fraction of PDU was
