We are leaking something

[samdroid-apps]

There might be a leak somewhere. 2 ways this is visible:

1. Do normal browsing for 10 minutes. After about 10 minutes, switching between tabs will result in a grey screen for ~5 sec and the browser becoming laggy. The toolbar (the Sugar stuff) is still responsive, but all of the web views are terrible.
2. Open a video (eg. https://www.youtube.com/watch?v=SYRlTISvjww). Press play. Hear the song for a little bit. Close the tab. The song will continue playing for a very long time (~30sec on my last trial, but I swear I have seen longer before). Are we not destroying the tabs when we close them? What is happening?

I'm unsurprised. I've seen this before. Try different methods of closing the tab; they can give different results because of which layer is doing the destroy. See PR #18 for prior discussion of similar tab leak.
