+Forwardable: Fix delegating to 'args' and 'block'
+
+* lib/forwardable.rb (def_instance_delegator) fix delegating to
+  'args' and 'block', clashing with local variables in generated
+  methods.  [ruby-core:72579] [Bug #11916]
+
+* lib/forwardable.rb (def_single_delegator): ditto.
+
+If you have a class that uses Forwardable to delegate a method to
+another object, and the method that returns the delegate object is
+called `args` or `block`, then Forwardable will fail to work.
+
+Here's a simple example:
+
+    class ModelCreator
+      extend Forwardable
+
+      attr_reader :args
+
+      def_delegator :args, :model_name
+
+      def initialize(args)
+        @args = args
+      end
+    end
+
+    ModelCreator.new.model_name
+
+If you run the last line above, then you'll get:
+
+    NoMethodError: undefined method `model_name' for []:Array
+
+This error occurs because `def_delegator` -- as it is written in Ruby --
+uses metaprogramming to add methods to the class that will then delegate
+to the delegate object. So it's as if we had written:
+
+    class ModelCreator
+      extend Forwardable
+
+      attr_reader :args
+
+      def model_name(*args, &block)
+        args.model_name(*args, &block)
+      end
+
+      def initialize(args)
+        @args = args
+      end
+    end
+
+As you can see, `def_delegator` will not only forward the method call
+onto the delegate object, it will also forward any arguments provided as
+well. It is here that the bug arises: it splats all of the arguments
+into a variable which is called `args`, and because of how variable
+scope works in Ruby, it then attempts to call `model_name` on *this*
+variable and *not* our delegate object method.
+
+The fix is to call the delegate object method manually using `__send__`.
+(This assumes, of course, that the given receiver is, in fact, the name
+of a method and not the name of an instance variable, which is also a
+possibility.) We use `__send__` because the delegate object method could
+be private.
+
+So, that looks like this:
+
+    def model_name(*args, &block)
+      __send__(:args).model_name(*args, &block)
+    end
+
+Because `def_delegators` and `delegate` use `def_delegator` internally,
+they also get this fix as well.

+RLIMIT_NPROC to 1 and triggering EAGAIN on pthread_create
+when attempting to recreate the timer thread.

+pthread_create fails               pipe looks valid, write!
+CLOSE_INVALIDATE (x4)              EBADF -> ASYNC BUG
+
+The checks in rb_thread_wakeup_timer_thread_low only tried to
+guarantee proper ordering with native_stop_timer_thread, not
+rb_thread_create_timer_thread :x
+
+Now, this should allow rb_thread_create_timer_thread to
+synchronize properly with rb_thread_wakeup_timer_thread_low by
+delaying the validation marking of the timer_thread_pipe until
+we are certain the timer thread is alive.
+
+In this version, rb_thread_wakeup_timer_thread_low becomes a
+noop.  Threading is still completely broken with NPROC==1, but
+there's not much we can do about it beside warn the user.
+We no longer spew a scary [ASYNC BUG] message or dump core
+on them.

+* thread_pthread.c (setup_communication_pipe): delay setting owner
