I have a shared memory segment called 0xdeadface, shown below.
When active, readable, writable, etc., it shows up in /proc/NNN/maps as (deleted). How/why would this be?
Also, `cat mem` in any /proc/NNN subdirectory returns "No such process" when `cat` tries to read it.
Output from cat /proc/MYPID/maps:
