 Here is a reduction of the bug encountered when a menu item calls a
 dynamically defined method.

 Run the following code and click on one of the two first menu items to
 reproduce the bug.

 {{{
 framework 'AppKit'

 app = NSApplication.sharedApplication

 class ItemDelegate

   def define_actions(actions)
     actions.each do |command|
       self.class.send(:define_method, command) do |sender|
         puts command
       end
     end
   end

   def quit(sender)
     exit
   end

 end

 @menu = NSMenu.alloc.init
 actions = ['test', 'test2']
 menu_delegate = ItemDelegate.new
 menu_delegate.define_actions(actions)

 actions.each do |action|
   item = @menu.addItemWithTitle(action, action: action, keyEquivalent: "")
   item.target = menu_delegate
 end

 item = @menu.addItemWithTitle("Quit", action: 'quit:', keyEquivalent: "q")
 item.toolTip = "Click to close this App"
 item.target = menu_delegate

 bar =
 NSStatusBar.systemStatusBar.statusItemWithLength(NSSquareStatusItemLength)
 bar.title = "test"
 bar.menu = @menu
 bar.highlightMode = true

 app.run
 }}}
