> Patch 7 is a related tidy-up/optimisation.
> Patch 8 fixes up a MySQL-only bug, but also adds some robustness.
> I think patch 9 closes the most likely issue for Buildroot patches.
> Pending review, patches 5, 6, 8 and 9 should go to stable.
> V2: Address review comments from Andrew, see patches.
> Added the new python script to the automatic pep8 testing.
> Minor improvement to parallel parse script to allow different
