private <T> void visitLimited(ThreadContext context, VisitorWithState visitor, long size, T state) {
  int startGeneration = generation;
  long count = size;
  int index = 0;
  // visit not more than size entries
  for (RubyHashEntry entry = head.nextAdded; entry != head && count != 0; entry = entry.nextAdded) {
    if (startGeneration != generation) {
      startGeneration = generation;

      if (entry == head) break;

    if (entry != null && entry.isLive()) {
      visitor.visit(context, this, entry.key, entry.value, index++, state);
      count--;
    }
  }
  // it does not handle all concurrent modification cases,
  // but at least provides correct marshal as we have exactly size entries visited (count == 0)
  // or if count < 0 - skipped concurrent modification checks
  if (count > 0) throw concurrentModification();
