I cleaned up the regression tests yesterday and added a benchmark suite:

  ftp://ftp.netbsd.org/pub/NetBSD/misc/freza/prop-regress-2007-10-09.tar.gz

The benchmarks revealed performance weakness in externalizer code, I've
fixed that in newer version (along with libsa compile botch):

Benchmark results below; lower percentage is better for the "winner".
