+/*
+ * NOTE: The structure of the routines is identical to that of POSIX
+ * Message_queues to leave the option of having unnamed message
+ * queues at a future date. They are currently not part of the
+ * POSIX standard but unnamed message_queues are. This is also
+ * the reason for the apparently unnecessary tracking of
+ * the process_shared attribute. [In addition to the fact that
+ * it would be trivial to add pshared to the mq_attr structure
+ * and have process private message queues.]
+ *
+ * This code ignores the O_RDONLY/O_WRONLY/O_RDWR flag at open
+ * time.
