After every scroll action or tab change, chromium updates it's
Current Session file. After it has written to that file, chromium
calls fsync().
This means that chromium, in combination with power management
causes a disk in standby mode to be restarted just to write the
current window position to the disk. This excessive fsync()
calling means that using chromium on a laptop can shorten the
life time of hard disks considerably (a single cursor key
press basically increases the Start/Stop count by one).
