This is quite helpful, thank you! I think this paragraph is relevant
to my use-case?

"Current file systems do not provide atomic multi-block appends;
appends can be broken down into multiple operations. However, most
file systems seemingly guarantee that some prefix of the data written
(e.g., the first 10 blocks of a larger append) will be appended

It sounds to me like I have this case covered with the "partial write"
failure mode of fail_file. Or is there another case I missed?
