The Process activity, like the Delay activity, will hold the token for a certain length of time. You can use a fixed time or you can create the delay time dynamically using a label value on a token, a statistical distribution, etc.
Additionally, the Process activity manages the resources involved in the process. These resources will have their state set to the user-defined state. For those resources marked as preemptable, the resources will be made available to be acquired by requests in a higher priority tier. The Process activity also allows you to define what should happen if a resource is preempted away.
