Description Du Liu 2022-10-16 05:09:15 UTC 
when xargs runs in parallel mode (using -P flag), it may sometimes return incorrect exit code. 

The following code shows current (incorrect) behaviour: /bin directory exists, /foo directory does not exist. `echo /bin /foo | xargs -n1 -P2 test -d` sometimes return 0 sometimes return 1:

```
root@freebsd:~ # test -d /bin
root@freebsd:~ # echo $?
0
root@freebsd:~ # test -d /foo
root@freebsd:~ # echo $?
1
root@freebsd:~ # echo /bin /foo | xargs -n1 -P2 test -d
root@freebsd:~ # echo $?
0
root@freebsd:~ # echo /bin /foo | xargs -n1 -P2 test -d
root@freebsd:~ # echo $?
1
root@freebsd:~ # echo /bin /foo | xargs -n1 -P2 test -d
root@freebsd:~ # echo $?
0
```
