> Currently, {{RocksDBIterator#close}} accesses {{RocksDbStore#openIterators}} without taking the {{RocksDbStore}} lock. The only lock {{RocksDBIterator#close}} holds is a lock on the iterator object, which does not help here. So {{RocksDbStore#openIterators}} should be made synchronized. Otherwise there is undefined behavior, including {{ConcurrentModificationExceptions}}.
