The issue is the audit subsystem being overwhelmed by potentially
useless information.

The initial report was "there's a bunch of null PATH records, please
make them go away", which was anywhere from 500 to 6000 records.

Once I found out what they generally were and a way to enumerate the
contents, we're reviewing that assessment to see if they really should
be tossed, or listed out in full.
