Note that this should only matter for files created in /tmp, but those files
need more than just 0600: they have to be created atomically.
Browsing through printing.el, I get the impression that it does not create
those files atomically.
When creating files in /tmp, it's very important for security reasons to use
`make-temp-file'.
