…t it (lambdaclass#54) A block whose parent has no post-state walks up to its first ancestor that does have a parent state and re-queues that ancestor for import. When the ancestor is held for its custody columns, that import can only hold it again, and a range batch hands the actor its whole chain at once, so every block behind a held one paid for another hold of it. On a mainnet follower's first batch after a checkpoint sync, the 68 blocks behind the first one re-held it 68 times over 54 s, while the columns that would release it had already been delivered. The walk now stops at a block in blocks_awaiting_columns. The child is already registered under its parent in pending_blocks, and the held block's release imports it and cascades down the chain from there.
