I was unable to find the relevant code with a quick look, but I didn't
take much time as I knew a short script would to do the trick.  I just
sorted on the serial numbers in the audit message.  Diff'ing showed
quite a bit of motion in the sorted output.  Also, I notice that in
just one message, the msg field value does not end with a colon:

type=DAEMON_START msg=audit(1185203485.586:824) auditd start, ver=1.5.5, format=raw, auid=500 pid=24638 res=success, auditd pid=24638
