		"description": "When I'm not using a {{Ti.UI.iPhone.NavigationGroup}} in my main/root application window, there will be a time I need to close the {{Ti.UI.Window}} wrapping the navigation group. But when I do, Instruments show it's leaking.\r\n\r\nConsider the following {{app.js}}:\r\n\r\n{code}\r\nfunction onClose(e) {\r\n  Ti.API.info('Closed: ' + e.source._id);\r\n}\r\n\r\nfunction closeNav() {\r\n  container.close();\r\n  // Uncomment for 2nd test-case: child.close();\r\n}\r\n\r\nvar application = Ti.UI.createWindow({\r\n  backgroundColor: 'red'\r\n});\r\napplication.addEventListener('click', function () {\r\n  container.open();\r\n});\r\n\r\nvar container = Titanium.UI.createWindow({\r\n  _id: 'container',\r\n  backgroundColor: 'green',\r\n});\r\ncontainer.addEventListener('close', onClose);\r\n\r\nvar child = Titanium.UI.createWindow({\r\n  _id: 'child',\r\n  backgroundColor: 'blue',\r\n  title: 'Window'\r\n});\r\nchild.addEventListener('click', closeNav);\r\nchild.addEventListener('close', onClose);\r\n\r\nvar nav = Titanium.UI.iPhone.createNavigationGroup({\r\n  window: child\r\n});\r\n\r\ncontainer.add(nav);\r\napplication.open();\r\n{code}\r\n\r\nNow do the following:\r\n# Run the app.\r\n# Click the red application window to open the navigationgroup holding a blue window.\r\n# Click the blue window to close the window containing the navigationgroup.\r\n\r\nThe console will show the following after step 3:\r\n{code}\r\n[INFO] Closed: container\r\n{code}\r\n\r\nAnd instruments will report the following number of living {{TiUIWindow}}'s after:\r\n# Living: 1 (the application window)\r\n# Living: 3 (the application, container and child windows)\r\n# Living: 2 (the application and child window I guess)\r\n\r\nNow, if you uncomment line 7 and follow the same steps the console will show:\r\n{code}\r\n[INFO] Closed: container\r\n[INFO] Closed: child\r\n{code}\r\n\r\nBut instruments will still report the same. So I guess, the child is kept hostage by some other native object?\r\n\r\nI would expect that closing the container window should be enough to properly clean up, but even the following doesn't give different results:\r\n\r\n{code}\r\nfunction closeNav() {\r\n  container.close();\r\n  container.removeEventListener('close', onClose);\r\n  container = null;\r\n  child.close();\r\n  child.removeEventListener('close', onClose);\r\n  child.removeEventListener('click', closeNav);\r\n  child = null;\r\n  nav = null;\r\n}\r\n{code} ",
