 	 * Document-class: SleepyPenguin::SignalFD

 	 * Use of this class is NOT recommended.  Ruby itself has a great
 	 * signal handling API and its implementation conflicts with this.

 	 * A SignalFD is an IO object for accepting signals.  It provides
 	 * an alternative to Signal.trap that may be monitored using
 	 * IO.select or Epoll.
 	 *
 	 * SignalFD appears interact unpredictably with YARV (Ruby 1.9) signal
 	 * handling and has been unreliable in our testing. Since Ruby has a
 	 * decent signal handling interface anyways, this class is less useful
 	 * than signalfd() in a C-only environment.
 	 *
-	 * It is not supported at all under (Matz) Ruby 1.8.
