These datasets are send to gnuplot via data files, so you can use those (=
their filenames), so you don't have to keep the data.

Gnuplot does not store data as
  double *x, *y;
but as
  struct gnuplot's_point_structure *pt
(for 3d organized in struct gnuplot's_iso_lines).

In principle, for future, gnuplot could be implemented for things like
reading from binary files like "/sharedmem/DataFromOctave" instead from
ascii data files (binary support is already in the "with image" patch by
Daniel).
