Actually, that's not always true. What you get is an "old" event when
the lease database changes. Normally, the client renewing the lease
changes the expiry time and therefore triggers this, but an infinite
lease renewed is still an infinite lease, so no joy.

You could just make the default lease time very long, so that it's
infinite for practical purposes, but the expiry time still changes when
the client reboots.
