/tmp is NOT mounted on swap - it's tmpfs, which is backed by swap. df -k
lies when it says "swap" for /tmp.

tmpfs will use up memory first, then swap.
That's only true if you think of 'swap' as being the stuff on disk.
Most utilities (and tmpfs) consider 'swap' the unified view of all pages
in RAM and swapfiles. So you might say that the VM system will tend to
allocate pages in RAM first, then on disk, but I would not refer to
either of those singly as "swap".
