If the DB library writer did their job (and I'm sure they did), they  
just are by the GC provided there are no references to them.

Typically you see code like this when you want to ensure cleanup:

class IO
   def open(filename, mode)
     io = new filename, mode
     if block_given? then
       begin
         yield
       ensure
         io.close unless io.closed?
       end
     end
     return io
   end
end
