at_exit is a standard part of ruby
% ri at_exit
--------------------------------------------------------- Kernel#at_exit
      at_exit { block } -> proc
------------------------------------------------------------------------
      Converts block to a Proc object (and therefore binds it at the
      point of call) and registers it for execution when the program
      exits. If multiple handlers are registered, they are executed in
      reverse order of registration.

         def do_at_exit(str1)
           at_exit { print str1 }
         end
         at_exit { puts "cruel world" }
         do_at_exit("goodbye ")
         exit

      produces:

         goodbye cruel world
