Gnuplot not responding

Dear all,

I use Octave to plot some data. I first plot the data on screen (X11). The
plot is made up of several plot commands with 'hold on'. I use several
elements (plot symbols and lines) to plot different things into one
figure. After this, the figure is saved to an eps file using Octaves print
function. The whole thing is done in a loop to produce the same plot for
different data sets.

The problem: Sometimes Octave hangs in the print command, telling that
gnuplot isn't responding. If I remove some elements (e.g. error bars) from
the plotting routine, the problem goes away. I guess gnuplot has a hard
time to keep up with Octave and gets overloaded, if there are too many
elements in the plot.

Is there a way to make sure gnuplot has finished everything and is ready
for new tasks before calling the print command?

I'm running Octave 2.1.73 with gnuplot 4.0 on Windows/Cygwin.
