  Log:
  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.
