This also caused a number of major regressions on our internal benchmarking framework.  I would like to see the change reverted while the public regression mentioned above is investigated.  We can provide some analysis of what went wrong in our internal environment, but I'd prefer to avoid investing that effort if we can diagnose from public benchmarks.
