A sweep counted every file the nodes were asked to delete as freed as soon
as it asked, and a node refused a set's directory as not empty, so tens of
gigabytes were reported freed and nothing was. The agent removes a set's
directory whole (a link only as a link), and the control plane waits for
each node to list its files again, saying what it no longer lists and what
it kept.
