Ah, ok. The info about sendsigs being ordered before udev on shutdown
was missing. I guess we need both then:
- udev using the sendsigs.omit.d interface to avoid being killed by
/etc/init.d/sendsigs
and
- removing the socket on stop and making sure udev is stopped in 0 / 6.

Anyone willing to work on a patch?
