--- Comment #4 from Chandler Carruth <chandlerc at gmail.com> ---
A long series of commits was needed to stabilize this, but I think it's looking
pretty good now.

Folks should be able to test it at r330264 or later. I'll seperately work on a
bug to pull together the full list of commits related to fixing this and
propose pulling them into 6.1.
