Subject: Events out of order

I captured a trace with blktrace -d /dev/sde -d /dev/sdf -o - > trace,
then parsed it with blkparse -i - < trace, and I have noticed that the
events are out of order. They appear to come in batches from one cpu,
then the other, and when transitioning from one batch to the other,
the timestamps roll backwards.
