Applies a function in the process that is associated with a wait-state-collection.
A function designator.
A process is associated with collection when it calls wait-for-wait-state-collection, typically from loop-processing-wait-state-collection. Normally only one process will do this for each individual wait-state-collection.
apply-in-wait-state-collection-process is asynchronous. It sends an appropriate message to the process or collection, and returns immediately, even if it is called from that process. The application happens at an undefined time inside the scope of call to call-wait-state-collection for collection.
