# This script crashes in ~40s on R 2.15.3 patched and R 3.0.2 with
# R.oo (< 1.18.0).  It only does so when 'methods' is attached.  It
# does not crash on R 3.0.2 patched (2014-02-21 r65057) and beyond.
# It appears to not crash with 'R CMD check' on 2.15.3 but if run
# via 'Rscript' or similar. /HB 2014-02-22
