I guess when ServerInvoker::setLeasePeriod is set to -1, we shouldn't change any previous estabilished Leases. That would change the behavior of futurue clients... and I guess this is how it's behaving now (if checking the property during setLeasePeriod) BTW when we call LeasePeriod to -1, we didn't have any Lease estabilished yet.
