Originally written by
- Alice is an ordinary write to a file on a file-system.
- Alice could be an attempt to write on an allocated part of the file...

- Alice could be a synced operation - waiting until she gets to disk-haven...
- ...or an un-synced operation - getting into the page cache is enough.
