I’m curious whether there is any guarantee that
leaked shared memory is reclaimed when a user logs out.
If a region is opened via shm_open but not closed before
the user logs out, is that memory reclaimed by the OS or does it persist until
reboot? My suspicion is that it is not reclaimed since there is no assurance
that the sharing processes are all running in the user’s session, but a definitive
answer would be great.
