Rik, Ben,
I've had an opportunity to try this out with numerous versions of
gnuplot. There is randomness to the window expansion. That is, it
isn't on ever plot that the window expands. That fact seems to
point to gnuplot as the source, and the problem seems to exist as
far back as gnuplot version 4.2.0. However, the expansion is at a
much slower rate, approximately once with every 200 to 300 plots.
With gnuplot version 4.2.5 the expansion rate is about once every 3
or 4 plots. There could be a timing issue made worse by new
additions to gnuplot over the years; one that shows up only when the
CPU is being completely taxed.
I'll look into the gnuplot side of things (and if you want to send
something to the gnuplot discussion list, feel free), but my advice
would be to not spend too much effort tracking down exactly where
Octave might cause a problem. It might just be a random arrangement
of code that works better than other versions.

I'd like to send something to the gnuplot developers. Unfortunately,
I'm unable to produce a gnuplot script that demonstrates the problem.
For some reason, I'm only able to demonstrate the problem when
communicating using the i/o stream (popen2) between octave and gnuplot.
Any chance you have a gnuplot script that demonstrates the problem?
