Welkin,

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.
