Well, what I was thinking is that whenever one of the interactive 
windows is closed, it would trigger gnuplot to exit and gnuplot's 
process would no longer be in the operating system.

Octave would just need to check if its registered process ID still 
exists.  If not, create a new gnuplot process.  It's still a bit dodgy 
though because someone could close the window while Octave is sending 
data through the pipe.  So, there would need to be some way of toggling 
said feature on and off.  I.e., turn the feature off until Octave is 
done sending data, then enable the feature.
