Yes, we should think much of privacy.  A better way would be to
set $TMPDIR, $TEMP, $TMP, and so forth to someting like "~/tmp".

Ok, I've restored a timer that tries to delete a temporary file
and its directory 1 minute after launching a viewer.
(Though the deletion will fail on Windows or Cygwin if a viewer
 is a Windows application, MS Office, AcroRd, etc. for example.)
