    CHANGES: snmpd: fixed infinite loop when SIGTEM arrives in middle of internal query processing.
    When snmpd starts internal query, e.g. for 'monitor' config options, it calls
    netsnmp_query_walk(). This function loops until either error occurs or the
    internal request is processed. And if SIGTERM comes to this loop, the request
    is not marked as failed.
