Review request for Plasma and Àlex Fiestas.


Repository: kwallet-pam


Description
-------

For example, currently if desktop is started by sddm.
For kwalletd5, it will be a subprocess of sddm-helper.
For kwalletd, there will be zombie subprocess.

Here we make use of the old trick to fork twice and collect the status of intermediate process with waitpid to avoid zombie process. --nofork is used for kwalletd case to avoid it fork yet another process.


Diffs
-----

  pam_kwallet.c a84585e 

Diff: https://git.reviewboard.kde.org/r/125190/diff/


Testing
-------

No more zombie process, kwalletd and kwalletd5 become subprocess of pid 1.


Thanks,

Xuetian Weng
