Chaining is possible. You can have multiple copies of the following code 
(changing the Mutex-specific part of course):

class Mutex
   module ForkSafely
     def fork
       super do
         ObjectSpace.each_object(Mutex) { |m| m.remove_dead }
         yield
       end
     end
   end
end

module ForkSafely
   include Mutex::ForkSafely
end
include ForkSafely
