> It will be helpful to add some logging to LeaseRenewer when the daemon is
> terminated (Info level),
> and when the lease is renewed (Debug level). Since lacking logging, it is
> hard to know
> if a DFS client doesn't renew the lease because it hangs, or the lease
> renewer daemon is gone somehow.
