I watch the processes, specifically the memory size parameter, as 
windows are open and closed.  (My window manager has a convenient system 
monitor for watching memory... but "ps" will do too.)  When a window is 
open, the memory size increases, naturally.  But when the window is 
closed, the memory size doesn't necessarily have to drop back down to 
its previous value because sometimes the heap isn't cleared immediately. 
 (Perhaps the kernel thinks the process will want the memory again.) 
 However, if you plot the same exact plot, the memory should not grow 
any higher than the previous.  In other words, keep plotting and closing 
the same plot; we shouldn't see memory keep on growing, just stay within 
some limit.

Now, for the unsolved leak, just resizing the very first plot should 
keep making the memory for the process "gnuplot_x11" keep growing.
