Sorry that you all experienced this. I wasn't able to get concurrent
queue accesses even with -c 8, so I spent about half a day last week
investigating a possible spinlock locking flaw. That meant the code in
that area was untested, which is most obvious now. I guess that means I
should test on different hardware in future.
