  The driver fails in the '_find_container_pid' method. The reason is
  that in 0.9 there is a new built-in execution driver used by default
  (libcontainer). Instead of cgroup path /sys/fs/cgroup/devices/lxc/ it
  uses /sys/fs/cgroup/devices/docker/.

  Could it be possible to rewrite _find_container_pid using the docker
  remote api and do not access cgroup filesystem directly?
