    MultiReadUnifiedSet provides a thread-safe wrapper around a UnifiedSet, using a ReentrantReadWriteLock. In order to provide true thread-safety, MultiReaderUnifiedSet does not implement iterator() as this method requires an external lock to be taken to provide thread-safe iteration. You can use an iterator() if you use the withReadLockAndDelegate() or withWriteLockAndDelegate() methods. Both of these methods take a parameter of type Procedure<MutableSet>, and a wrapped version of the underlying Unified is returned. This wrapper guarantees that no external pointer can ever reference the underlying UnifiedSet outside a locked procedure. In the case of the read lock method, an Unmodifiable version of the collection is offered, which will throw UnsupportedOperationExceptions on any write methods like add or remove.
