"In order" does not necessarily imply "one node at a time".

I don't consider it unreasonable for two nodes starting (effectively)
simultaneously to appear in the first membership.
I believe Heartbeat had the same property.

Why not just take a lock when you want to create the daemon_protocol
section (and allow the second guy to fail gracefully)?
Perhaps cpg even has something like this built in...
