Sorry for the delay, broken laptop, vacation, etc.

Here's a baseline against 8.0.1:
        http://www.osdl.org/projects/dbt2dev/results/dev4-010/309/
        throughput 3639.97

Against CVS from 20050217 and the 2Q patch:
        http://www.osdl.org/projects/dbt2dev/results/dev4-010/311/
        throughput 3875.84

About a 6% increase, but if you look at the performance over time,
it's degrading steadily.  The latter throughput peaks near 5000.
