Believe a few of these are understood:

These are caused by "readahead": readahead delays starting up auditd
until it has "finished". Apparently it does this in a manner not 100%
as expected. I got rid of these by uninstalling readahead.
Believe the developers are aware of this.,....
Believe many of the earlier AVCs are due to recent changes to the
"unconfined" domain. From dwalsh: "I have changed all
unconfined_domains to permissive so that we can find as many AVC's as
possible for a couple of weeks."
