It would livelock

I wouldn't call it a livelock, because I wouldn't expect the runtime to be doing any (useless) work on behalf of the program.

Still, trading deadlocks for livelocks is a net negative as they are harder to identify and diagnose.

		Paxos necessarily livelocks and still seems useful. More generically, all nonblocking algorithms which are only “obstruction-free” can livelock, but techniques like randomized backoff can make them quite reliable in practice (just like Paxos/Raft).
