Not so --- as was pointed out later in the thread, neither NFS nor AFS
work that way, and there could be other cases.
In any case, I don't subscribe to the idea that we can just abdicate all
responsibility in case of hardware problems. Yes, we do rely on a disk
to keep storing information once it's accepted it, but that doesn't mean
that it's okay to ignore write-failure reports. We are failing to hold
up our end of the deal if we do that.
