The order was 0 1 1 2 2 3 3 ....
I dont know why it did not abort, but it ran for hours as I can see from
the output of the time command at the end of my log. I am pretty sure I
did not start this run twice the same time, this would leave behind
output from our queing system, but it did not.
Also it is quite sure I did not overwrite old data, since my submission
scripts move the old run folder out of the way automatically.
To be sure, I just restarted the run in a clean directory. It'll take a
while before I see first output.
