reachabilityBarrier top-level property
Current reachability barrier state.
A reachability barrier state that provides a way to synchronize on reachability. At value 'x', any object that became unreachable during 'value' < 'x' has been collected and any associated finalizers have been scheduled for execution, i.e. the non-execution of a finalizer reliably indicates the object is still reachable in the previous barrier state.
Objects that became unreachable in the current barrier state may have not yet been collected or finalized.
NOTE: There are no guarantees of forward progress. An implementation may return the same value forever for this barrier state.
