I have updated the patch
[ 2570385 ] GPVAL_X11_WINDOWID
https://sourceforge.net/tracker/?func=detail&atid=302055&aid=2570385&group_id=2055
with Ethan's solution and an additional wrapper over GE_plotdone sender. 
Now, only changed window ID's are sent to gnuplot for the variable 
GPVAL_TERM_WINDOWID to be updated.

Ben, can you please test it? Would it suite the needs in Octave?

BTW, I've tested the freshly released octave-3.1.52 and I'm disappointed 
about the plotting window behaviour. Gnuplot graph window gets always closed 
and reopened, but not at the previous position, but at some default 
position. Moreover, it hijacks the focus. Hitting the "space" hotkey helps 
to go back, however, is this behaviour really desired? Octave is executing
	set term x11 close size nnn,nnn position nnn,nnn
I think the repositioning command should be issued only if user has 
explicitly changed it. Do I have to recompile Octave in order to get rid of 
this behaviour, or is there some magic "set(gca)" to put the window to 
the screen corner?
