It would also affect current KDE desktops as they tend to use MySQL for
Akonadi & Nepomuk, plus anyone using Chromium (and presumably Chrome):

samuel@eris:/tmp$ sudo lsof | grep deleted | awk '{print $1}' | sort |
uniq -c
[sudo] password for samuel:
     32 chromium-
      1 dovecot
      5 imap-logi
      5 mysqld

I would be surprised if you could find many systems that didn't have
files in this situation.
