    sh: Remove duplicate code resetting uid/gid for set +p/+o privileged.
    
    sh: Check setuid()/setgid() return values.
    
    If the -p option is turned off, privileges from a setuid or setgid
    binary are dropped. Make sure to check if this succeeds. If it
    fails, this is an error which will cause the shell to abort except
    in interactive mode or if 'command' was used to make 'set' or an
    outer 'eval' or '.' non-special.
