+ * For legacy compatibility, this is disabled by default. In newer programs / releases, it is recommended to enable this
+ * feature during main() startup, since it greatly simplifies deallocating child, parent and other FSM instances without
+ * running into double-free or use-after-free scenarios. When enabled, this feature changes the order of logging, which
+ * may break legacy unit test expectations, and changes the order of deallocation to after the parent term event is
+ * dispatched.
+ *
+ * When enabled, an FSM instance termination detects whether another FSM instance is already terminating, and instead of
+ * deallocating immediately, collects all terminating FSM instances in a talloc context, to be bulk deallocated once all
+ * event handling and termination cascades are done.
+ *
+ * For example, if an FSM's cleanup() sends an event to some "other" FSM, which in turn causes the FSM's parent to
+ * deallocate, then the parent would talloc_free() the child's memory, causing a use-after-free. There are infinite
