OK, here is perhaps a better test.  In one window, execute the commands

  mkfifo fifo
  gnuplot < fifo

and then in another

  cat > fifo
  set mouse
  plot sin(x)
  ... other plotting commands ...

On the OS X system, does this show any different behavior than
Octave+gnuplot?  If so, then there might be a bug in the way Octave is
communicating with gnuplot.  Otherwise, if the behavior is the same
then I think the problem is not in Octave.
