Ha, this does not affect me personally, because of the way I use Chromium. Instead of calling it directly, I call a script which copies white-listed files and directories from the main Chromium data directory to a new data directory in /tmp, and then starts Chromium with the new data directory as data directory. After the directory in /tmp is deleted, there are sure to be no more cookies from that session.
