trait ActorGC
[source: scala/actors/ActorGC.scala]
trait ActorGC
extends TerminationMonitor
ActorGC keeps track of the number of live actors being managed by a a scheduler so that it can shutdown when all of the actors it manages have either been explicitly terminated or garbage collected. When an actor is started, it is registered with the ActorGC via the newActor method, and when an actor is knowingly terminated (e.g. act method finishes, exit explicitly called, an exception is thrown), the ActorGC is informed via the terminated method.
