AtomicReference

class AtomicReference<T>

An atomic reference to a frozen Kotlin object. Can be used in concurrent scenarious but frequently shall be of nullable type and be zeroed out once no longer needed. Otherwise memory leak could happen. To detect such leaks kotlin.native.internal.GC.detectCycles in debug mode could be helpful.
