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