I've been configuring a server for a colocation recently using ubuntu 12.04 desktop (the server dist dislikes my only keyboard) and I noticed that if I am running an fio test and I initiate a shutdown the shutdown kills off everything as usual, but fio appears to keep running and block shutdown. (from either the desktop ui or with "shutdown now") Thus on a remote server any user with privileges to run fio could accidentally, or maliciously prevent system shutdown from completing, effectively taking a server out of service until physical access was achieved.
