The cluster manager (cman) locking scheme uses kernel modules to communicate cluster status and changes between nodes. OpenAIS uses userspace programs to accomplish the same thing. Moving this function to userspace made more sense since it makes it easier to monitor and debug, non-fatal if it crashes, and it meshes better with the communications layers of the operating system.
