This is moving towards node suicide; that's something which probably
should be handled a little bit differently, and also needs to take into
account whether all nodes see the loss of the ping nodes (in which case
fencing is a bit pointless), the partition of the node, etc.
Instead of seeing implementation requests, I would much rather see the
intended use case. (That holds for all of them.) One thing which we need
to get a lot better at is ensuring design consistency.
