It would be nice to get lockutils graduated to solve some of the issues
mentioned in the oslo.db section, but I believe we do have an
outstanding question regarding its behavior without lock_path being set.
I think Clint was on board with Sean's proposed solution after quite a
bit of discussion
so it's possible we could just restore that patch and call it done, but
it should probably be addressed somehow before graduation.
