Changing /etc/init/network-manager.conf as mentioned here did not fully solve the problem for me.
Instead, it led to network-manager complaining about a missing messaging bus (DBus?) during shutdown (which was still too long ;) ).
The workaround mentioned in Bug 903825, however, seems to work perfectly.
