Hi Ryan,

Thanks for cooking up these patches.

A quick review on my part found nothing and I am going to ask the SRMs
if this approach is ok (usually we are not much for relying on people to
upgrading to the latest point release before a major upgrade).

Related:

 * Can we trivially document the steps so the user / admin can perform
   this manually (assuming they do not upgrade their stable version
   first)?
   - If so, then I will add that to the release notes.

 * The next point release is probably going to be later this month.  The
   current (but not yet announced) dates means that the stable fix
   probably has to be uploaded before the end of the next weekend at
   the latest.

Thanks,
~Niels
