It is cause of memory constraints (which manifest themselves in various ways). It's also possible that it's the cause of threaded interaction behaviour between when the downloads finishes and the UI at the time. Some people have indicated that there are issues with displaying a UIAlertView and creating a UIWebView, when the latter is created before the former. If you have a quick download connection (which is likely to be the case in the simulator and a local web server) then you might find it's the fact that your download is finishing too quickly for the UI to be ready to display a notification that the download is complete.
