The requirements generally care about resource access. File open, connect,
accept, etc. We don't care about read/write itself as that would flood the
analysis.

I'd say maybe a quarter to a third look interesting.

There is that...

People that care about auditing are under regulatory mandates. They care more
about the audit event than the performance. Imagine you have a system with
some brand new medical discovery. You want to know anyone who accesses the
information in case it gets leaked out. You don't care how slow the system
gets - you simply *have* to know everyone who's looked at the documents.
