As far as I know, on Unix short-lived files (and pipe data) are never
physically written to disk, they just live in the fs buffers in memory.
I imagine this is still true in all current operating systems that are
capable enough to run Octave.

Sure, you get all the fs overhead, so I agree that in principle it is
bad engineering, I do not think that the mass memory would suffer from
that.
