Original commit message from CVS:
2005-02-24  Andy Wingo  <wingo@pobox.com>

* tests/mass_elements.gnuplot: gnuplot file for the mass_elements
benchmark. Run as gnuplot mass_elements.gnuplot > foo.ps, after
running bench-mass_elements.scm.

* tests/bench-mass_elements.scm: New script, runs mass_elements
for various numbers of identities, outputting the results to a
file. Requires guile 1.6. Just for testing.
