Sorry, I don't think that contextDestroyed is quite the right thing. I think
you want to override stop(). contextDestroyed is when the context is finally
deallocated (e.g., it's called in the destructor). This stuff is kind of
obscure. I should write some documentation explaining the lifecycle of these
objects.

Please add the following line here:
RefPtr<Intent> protector(this);
We don't control the lifetime of |this|, so we have to assume that handleEvent,
which can do arbitrary things, can remove all existing references to us. That
means we need to take a reference to ourselves because we assume that |this| is
still alive after handleEvent returns.
