title: (lots of) UIWebView memory leaks
body: <p>I've seen from other posts that there are memory leaking issues with UIWebView.
  However, with the amount of objects that I have leaking, I have to wonder if I'm doing something wrong.  'Leaks' reports about 60 leaks for opening a UIWebView, loading a page and closing (it's the Facebook login page).  I've check the stack trace for every one of these objects, and they never touch my code.  They're all either in a separate thread (I only use the main thread), or go from 'main' to a bunch of internal methods that are greyed out.  Is this expected from UIWebView?  I'm running the latest firmware, and I think they would have fixed this by now.
  I'm seeing this on the device, by the way.
  I also tried checking for bugs on the apple site, but there's no way to search other than by issue ID..?</p>
