If you are building octave and would like to permanently change the default 
name for gnuplot, you can set the name during configure.

Otherwise, “mlock ()” can be added to gnuplot_binary.m. This will prevent 
gnuplot_binary from being cleared and should also preserve the persistent 
variables “gp_binary” and “gp_args”. imo, “mlock ()” should be present. Perhaps 
this is a bug?
