Or plan ahead. If you know you will be changing some lease options you
should set the lease time down to something small at least
$(current_lease_period) seconds ahead of time. Then you can be fairly
certain that all systems will get a new lease within
$(new_lease_period) seconds of you change. Afterwards you can increase
the lease period back up. Of course, this assumes you were not handing
out "infinite" lease periods.
