   Any external input. So also every OS call (since it usually can fail leading   
   to an alternate codepath) and of course RAND()   
      
   Note that if such calls are wrapped in your runtime, and are "under the   
   hood" it still applies, unless the compiler has very inimate knowledge about   
   the runtime.
