I don't know why your particular system didn't swap, but that's not true in general, e.g.: https://www.kernel.org/doc/Documentation/filesystems/tmpfs.txt "tmpfs puts everything into the kernel internal caches and grows and shrinks to accommodate the files it contains and is able to swap unneeded pages out to swap space."
