> I haven't seen this yet in practice, but I think the following is a bug:
> - Clients currently only renew leases to the active NN
> - Leases are written into the log when created, but there is no record to
> renew them
> - In Standby state, we don't check leases for expiration. But, when we fail
> over and start the lease monitor, since the leases haven't been renewed, they
> might end up getting incorrectly released.
