Possible Effects of Delayed Preemption

Several circumstances can be created through the use of preemption process records. An entity delaying a preemption, for example, may find at the conclusion of the delay that the preemption is no longer required, or that it faces an even higher preemption priority.

In cases where an entity has multiple locations or resources from which to choose, a preemptive request for any one of them is not necessarily a commitment to select that particular location. If any of the alternative locations becomes available, the entity will select it and withdraw the preemption request.
