 OS: RHEL4, gcc 3.4.3

 A process creates a named shm segment by instantiating class
 managed_shared_memory with create_only mode set and unrestricted
 permissions (-rw-rw-rw-)
 Another process launched by the same user attaches the shm using open_only
 mode. Permissions of the shm segment get changed (-rw-r--r--)
