So this was a misunderstanding - I wasn't implying that he throw the
exit status away, on the contrary. Check what the comment said

And that do something might involve something which isn't safe
to run from a signal handler.

Otherwise if he isn't interested in the status code, then yep - your
advice is quite correct
