> Here's a potential bug case that we don't currently test for:
> - SBN is reading a finalized edits file when NFS disappears halfway through (or some intermittent error happens)
> - SBN performs a checkpoint and uploads it to the NN
> - NN receives a checkpoint that doesn't correspond to the end of any log segment
> - Both NN and SBN should be able to restart at this point.
