Thanks for your excellent work in doing this benchmark time-series,

however I want to point out that the Pentium4 has about the worst
lock overhead of all cpu architectures, even on UP.  This may cause
certain changes to look much worse than they are on currently popular
architectures.

For an estimate and time-series comparison your bench test is very
helpful though.
