Thank you. It appears that this is somewhat similar to what happens in a very old bug (188925). Not sure if this is some kind of regression or if this is 'how things are supposed to be'. On reboot lsof only shows init being in use, with some of the libraries (incl. libc6). So right now I can only believe that the update of libc6 is causing this issue. I also tried restarting upstart (telinit u), but that apparently either doesn't work or it does work but doesn't solve the issue.
