   innocently looking regular expression <code>a?{28}a{28}</code> and match it, say, against the string 
   <code>aaaaaaaaaaaaaaaaaaaaaaaaaaaa</code> (that is 28 <code>a</code>s), you will soon notice that your CPU usage goes to 100%. In fact,
   Python and Ruby need approximately 30 seconds of hard work for matching this string. You can try it for yourself:
