Ran these overnight on 2 machines on top of recent BFQ and nothing
caught on fire. One funny benchmark result stood out since it gave
me (repeatedly!) 560 MB/s read bandwidth on an SSD which is rated to
do "up to 550MB/s", so I guess BFQ's bandwidth guarantees are now
really quite strong. :-)

Therefore:
