SVN rev 184489 on 2008-10-30 23:09:19Z by rwatson
When we drop an audit record going to and audit pipe because the audit
pipe has overflowed, drop the newest, rather than oldest, record. This
makes overflow drop behavior consistent with memory allocation failure
leading to drop, avoids touching the consumer end of the queue from a
producer, and lowers the CPU overhead of dropping a record by dropping
before memory allocation and copying.
