Sorry for bothering you, but to prevent you from re-inventing the

accept one. The simplest would be to define:

     def Lock.new(*dummy)
        ...
     end

BUT you have a problem here. File.new is one of the constructors, that
*DO*NOT* call initialize afterwards. So your Lock#initialize didn't
get called!!!

Let the other problems remaining ... :-)
