[...]; file opened for writing, bytes written, file closed.  You
could argue that until the file is closed, the file isn't written to
disk (if you look at the directory entry of a file that's interrupted
at that point, you have a zero-byte file).

Under what OS?  Certainly under a Unix variant, the only way I can see
this happening is if (a) the file is small (under stdio's buffer size),
(b) the program writing it uses stdio to do so, and (c) by "written"
you mean "passed to stdio" rather than "flushed to the filesystem".
