This topic might be more appropriate for the maintainers list, so I'm cc'ing there.

From what I recall, Octave currently launches a separate instance of gnuplot for each figure. (Because gnuplot only saves the data/state for the most current plot.) But I'm not sure if what you describe is the intended behavior or not, i.e., that gnuplot hangs around in case Octave needs to use it again. If not, perhaps you could give a more detailed description with examples. Maybe the behavior can be improved.
