Heh, I always thought openvz locks a file in $LOCKDIR to signal that
the container is running, but now that I look in the straces it looks
like it uses a custom ioctl, which is local kernel scope only.

Would probably be a nice feature request to use a flock or at least
leave a lockfile somewhere that can be mounted as a poor man's fencing
mechanism.
