Review request for Plasma, Àlex Fiestas and Martin Klapetek.


Changes
-------

add mklapetek as reviewer


Repository: kwallet-pam


Description (updated)
-------

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

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
