commit 8088761c016eecba6d3e223fdc2965353577d735 Author: Michael Schloh von Bennewitz <michael@schloh.com> Date: Thu Jun 5 03:53:15 2014 -0700 Bug #9701: Prevent ClipBoardCache from writing to disk. This disables the disk activity entirely. It seems as though there is no reason in to write backup copies of clipboard data to disk, as the clipboard code does not release the related memory upon disk writes anyway.
