I would like to have a shot at this if no one else if currently
working on it. This would be my first attempt to graduate from
testing (and a few simple patches) to an actual functional change. I
would expect that the steps involved are:

- See what data is affected under the BKL
- See where else that data may be affected (including possible
parallel calls to the same path)
- Decide what locking is necessary
- Implement it (the easy part)

If this is about right (and I'm not missing anything major) - I will
give it a try and see where I get.

If, however, I have just proved that I do not have a full grasp of the
problem, or if someone else is already working on this particular path
- please let me know.
