On my system octave didn't crashed - returned to prompt in about 1s, but
gnuplot will render it probably in hours or even days (on my Athlon 1600XP).

With gnuplot I seldom use meshes bigger then 30x30.

You can plot such mesh with jhadles plotting backend in some seconds. On
older computers memory usage can be a problem - results for my Linux box:

octave 3.0.1 + gnuplot 4.2.2 (unfinished state)
  octave   58/98 MB (first value: mem really used, second: allocated
                     - for Windows the second is important)
  gnuplot  195/209 (and still growing about 1MB/min )

octave 3.0.1 + jhandles 0.3.4
  octave 152/394 MB
