@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!
