Hmm. This patch looks obviously correct. But it looks *so*
obviously correct that it just makes me suspicious.

Nevertheless, being too afraid to stray from the beaten path
implies being too afraid to work on RCU. But there are times when
the RCU implementation needs a more sane approach. During those
times, I must find some other outlet for my insanity: To do
otherwise is to break RCU. Fortunately, this time around, an
appropriate outlet was readily available in the guise of Ubuntu's
new Unity window manager.
