 <p>
 Currently it is an error if the lockID is not found. Because if
 we can't find it we cannot refresh it.
 </p>
 <p>
 Since locks are time sensitive it is impossible to check
 if a lockExists and then be sure it will still exist when you try to
 refresh it. Nothing we do can protect client code from this fact, they
 will need to do with the IOException when (not if) this situation
 occurs.
