Comment 17 for bug 533157

Good. Pkill -9 (SIGKILL) is not intercepted because that is a signal that is only sent by the user, if he actually wants to kill the process. it's the default signal for killall, kill, pkill & co.
I think that we shouldn't save changes in that case, since the process has been voluntarily killed.
If anyone thinks that it should also be trapped, speak up!
