Yes, we are.  That is another topic, and another set of changes I've
been deferring so as to not disrupt the audit container ID work.

I was thinking of what we do inside the kernel between when the record
triggering event happens and when we actually emit the record to
userspace.  Perhaps we collect the ACID information while the event is
occurring, but we defer generating the record until later when we have
a better understanding of what should be included in the ACID list.
It is somewhat similar (but obviously different) to what we do for
PATH records (we collect the pathname info when the path is being
resolved).
