- SVR4.2 with the Veritas file system does a sync() on last write. Univel
- claims that a secretary will be able to type a letter in Word Perfect, save
- the file, and then hit the power switch. I believe that Veritas is a
- journaling file system, and they obviously have sync() written to return
- on successful execution rather than successfully being scheduled.

- Maybe someone will reverse engineer the Veritas FS. :-)
