pub fn notices(
blocked: &[Blockage],
holders: &BTreeMap<NodeId, String>,
) -> Vec<Notice>Expand description
One line for each resident holding work behind a red node.
A resident is told once per blockage rather than once per node it holds: a mailbox with four copies of one problem is a mailbox nobody reads. The resident that caused the blockage is not told about its own — it is the one that reported it.
