That's not true. Swap will come into play and unreferenced data in
the /tmp files will be paged out in favor of claiming that memory for
other uses.
It's still a win, however. If and when some file that was paged out
is opened or read again, it will be paged back in. That can be faster
than normal file I/O.

This was discussed in great detail before the change was made.
