WSGI doesn't like sys.exit() being called, so avoid it. Two cases need to be taken into consideration:
1. No exception thrown by self.args.func()
The variable exit_status is zero, we can check that and _not_
call sys.exit()
2. Exception thrown by self.args.func()
In that case, the exception should be raised, to be caught by
WSGI / ASGI whatever to do what they want with it. The code
calling sys.exit() is never reached. Hence, we need to add
--backtrace to the invocation options.
