Thank you James for your viewing.

* In general, it can give a more fine grained and flexible DAC to msg queue obj.
* NFSARK(A distro) wants all posix ipc objects to support ACL, including mqueue.
* Posix semphore and shmem both support ACL, but mqueue as one of the
three basic ipc doesn't.
* At least, it may save one note sentence for MQ_OVERVIEW(7) ^_^
"Linux does not currently (2.6.26) support the use of access
control lists (ACLs) for POSIX message queues."
