This is an excellent idea for, eg, a collection of servers, or any
client population (even desktops) where the systems do not shutdown
or reboot often.  Actually, larger numbers are even better ideas (I
know of an installation that uses ~6 month lease times for server

It is not so excellent an idea for 'laptop populations' or any which
tend to be turned on and off daily...this activity trumps the lease
times, and leaves stale leases hanging (the problem being reported).

Since this configuration parameter can be scoped, it might not be
a bad idea to select long times for static populations (employee
networks?) and short times for highly dynamic populations (student
or guest networks?).
