What you really ought to do is hand the lease to a LeaseRenewalManager,
so that the lease is properly renewed and the transaction lasts as long
as you need it.  The concept of a "transaction timeout" that you see in,
for example, database transactions, is really just a nod to the fact
that services have to release resources at some point.  The Lease
concept addresses the problem directly.  When the lease holder stops
renewing the lease, the service can release any resources associated
with that lease.
