stk: do we have a but tracking changing all those "__unsafe_unretained" to
"__weak" in headers once all our code is using ARC?

No, I'm planning to do it by hand by searching for all __unsafe_unretained :) I
can create a bug to track this, but I don't think we should log individual files
to fix since it's easier to just cmd+F
