VIM REFERENCE MANUAL by Bram Moolenaar
When on, the library function fsync() will be called after writing a
file. This will flush a file to disk, ensuring that it is safely
written even on filesystems which do metadata-only journaling. This
- will force the harddrive to spin up on Linux systems running in laptop
- mode, so it may be undesirable in some situations. Be warned that
- turning this off increases the chances of data loss after a crash. On
- systems without an fsync() implementation, this variable is always
- off.

This is a |global-local| option, so it can be set per buffer, for
example when writing to a slow filesystem.
Also see 'swapsync' for controlling fsync() on swap files.
