Anonymous functions are BAD.
So if I am following along correctly here, what I believe is happening is
that because of the anonymous function in the timer handler, the GC doesn't
have a reference to clean up. If you change from an anonymous function and
define the function you get much better results. See my example below. It
calls the tick function 10 times and after that the click handler is cleaned
up. Change back to the anonymous handler and it isn't.
