Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.
Not sure about this one.
Is this only "heuristic", or do you have something in pacemaker source
you can point me to?
If we are unsure, we better assume that the node should be fenced,
rather than assume that is was clean down when it actually is not
(even though it may already have had announced its intention to shutdown).
