That is actually what I was doing - no idea why the ps output suggests
that the 4.0.1.13-postinst is being called.

I used

ps ax | grep x2gocleansessions | grep perl \
| awk ' { print $1 }' | xargs -n 1 kill

instead as I came up with that before you replied.
(I wasn't sure if killall does more nasty things, and the system I was
trying it on was already b0rked enough.)


... so I skipped this part ...

... because this happens immediately after the kill:
