http://pubs.opengroup.org/onlinepubs/009604499/functions/shm_open.html "When a shared memory object is created, the state of the shared memory object, including all data associated with the shared memory object, persists until the shared memory object is unlinked and all other references are gone. It is unspecified whether the name and shared memory object state remain valid after a system reboot." see the last sentence ?
