Over the weekend, Thomas got a chance to review the leap second fix
in more detail and had a few additional changes he wanted to make
to improve performance as well as style.

So this iteration includes his modifications.

Once merged, I'll be working to get the backports finished as quickly
as I can and sent to -stable.
