Seems that with FIFO fairness, /bin/sync now also livelocks. And
it's pretty easy to see why. There's nothing to make
write_unlocked_buffers() terminate.

We'll worry about that tomorrow. I may just make it give up
after writing (2 * nr_buffers_type[BUF_DIRTY]) buffers.

The patch works well with read-latency2 (and it didn't throw
rejects). Smooth and fast. It's going to take some time and
testing to settle everything in.
