Robert,

Can you please take Ted's feedback into account (this and his response
to patch 10/10) and prepare another version of the patches.

As Ted suggests here, please run the regression test suite prior to any
future patch submissions. Looks like we missed some critical bits by not
doing that.

Ted, thank you for the response and taking the time to point out the
test suite. Robert, could you check the README and see if anything needs
to get updated there to make sure other developers are aware of the
regressions suite and how to run it?

Thanks,
