+ @vindex write-region-inhibit-fsync
+   When Emacs saves a file to disk, it issues an @code{fsync} call to the
+ operating system to ensure that your data has indeed reached the media.
+ This is important for safety if the system crashes or in case of power
+ outage.  However, it can be disruptive on laptops using power saving
+ because it forces the system to spin up the drive each time you save a
+ file; the variable @code{write-region-inhibit-fsync} disables this
+ synchronization.  This may result in data loss, use with care!
