Maybe. To start dumping entries of an open hashed hash-table at a
specific position we need to skip all entries before that position by
walking over them. This results in quadratic time complexity. It might
be possible to improve this by cacheing the last position in
fib_iter_state even between ->stop() and ->start() calls and using
generation IDs for invalidation.
