Kill child process before task process.

[ArthurJam]

When you killed a task, you first closed the task before killing its children and therefore their were not closed.
Now I act in the other way, by killing the children before.

Sorry, but i think this is non-sense. In *nix you can kill parent without it's children. And all will be ok, parent process will be killed, but children still alive (and you can kill its next).
You can check this by simply way - https://stackoverflow.com/questions/8533377/why-child-process-still-alive-after-parent-process-was-killed-in-linux

Hi,

Actually the command to kill a task is in 3 steps :
1 Kill the parent process (kill -9 pid)
2 Get the children process from parent (pgrep pid)
3 Kill children process kill -9 pgrep pid

But in practice (in my platform), the children are not killed by this processus.
I think you cant pgrep a pid are already killed, so you can't get the children process list (Unless the first kill command takes a certain delay).

So, i propose to inverse the scenario.

OK, thanks, i change order of kill requests.
