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?
