+ *  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.
