I cannot explain any of that.  It works normally for me here.
A qt window pops up immediately with four embedded gnuplot widgets
and a text pane.  Output from gnuplot appears in the text pane.
The demo replots to one of the widgets every second or so and
continues to do so until I close the window or hit Ctrl-C in the
controlling terminal.   No zombies either :-)
