I also have been getting this "bug" on two machines, each with a fresh Xubuntu 13.04 install.
----------------------------------
umount: /run/lock: not mounted
umount: /run/shm: not mounted
mount: / is busy
----------------------------------
Shutdown process would take about 10-12 seconds, instead of the expected (for me) 2-3 seconds. Once in a while, it would trigger 'fsck' for a scan at bootup.
After unchecking "Available to all users" on eth0 through network-manager, the problem is no longer present and my shutdown is clean. Will do the same on my second machine and report.
