The basic idea is that you want to get a malfunctioning node out of the
way as quickly as possible so others can recover and carry on.  Escalating
a partial failure into a total node failure is the best way to do that in
this case.  Specialized recovery paths run from a partially failed node
won't be as reliable, and are prone to blocking all the nodes.

I think a reasonable alternative to this is to just sit in an infinite
retry loop until the i/o succeeds.
