Yes. A process might be a more ontologically appropriate comparison than a computer user.
"So and so has exited with code 0 and his/her resources have been reclaimed by the system"
A human being is more like an event (a fire, a OS process) than like a persisting object.
Once a process (/fire) has ceased running (/burning), you can start a new process (/fire), but it wouldn't be considered an instance of reviving the old process (/fire), which has ended for good.
Passed on
Expired and gone to meet its maker
Gone off the twig
Kick the bucket
Pushing up daisies
Shuffled off the mortal coil
Run down the curtain
Joined the choir invisible
