This is wishful thinking (unless we fix the current set of bugs
that prevent us from doing so even in a healthy filesystem for example
PR/30525). I would be happy if we could isolate the broken filesystem
from all I/O operations instead of crashing.
Yes -- I meant that as a long-term (medium-term?) goal, not as
something we can just do right now.
