Audit log can be written to a named pipe, just replace the real audit 
file with a fifo.  You'll still need to disable log rotation.  Logging 
to a fifo has been a trick used in the past to capture the last few 
thousand lines of a high level of error logging with minimized 
performance impact, using a tool that provided a circular buffer in memory.
