  Log:
  - Change the wakeup logic associated with having multiple sleepers
    on multiple different audit pipes.  The old method used cv_signal()
    which would result in only one thread being woken up after we
    appended a record to it's queue.  This resulted in un-timely wake-ups
    when processing audit records real-time.
  
  - Assign PSOCK priority to threads that have been sleeping on a read(2).
    This is the same priority threads are woken up with when they select(2)
    or poll(2).  This yields fairness between various forms of sleep on
    the audit pipes.
