  Log:
  Only signal the CV indicating that the MAC Framework is available for
  exclusive access if there is at least one thread waiting for it to
  become available.  This may significantly reduce overhead by reducing
  the number of unnecessary wakeups issued whenever the framework becomes
  idle.
  
  Annotate that we still signal the CV more than necessary and should
  fix this.
