My idea on how to deal with this would be to mark the function to be
"AUTONOMOUS" similar to how a function is marked to be "PARALLEL
SAFE",
and to throw an error if a caller that has blocked autonomous
transactions tries to call a function that is marked to be autonomous.

That way none of the code that needs to be audited would ever get executed.

I like this idea - it allows better (cleaner) snapshot isolation.
