OK. Can you think of a use case that would break if wait -n looked at terminated processes?Yes. If one were to start a number of bg jobs and repeatedly send the list of pids to wait -n (probably redirecting stderr to /dev/null to ignore messages about unknown jobs) today you'd process the jobs one at a time, assuming no races between job completion. If wait -n looked at terminated processes you'd return jobs repeatedly and possibly end up in an infinite loop.
OK, that argues for a new option to provide this functionality.
