Seen in an exception stack trace: we are wrapping `ApiFilteringActionFilter` around itself many times, once per filtered action, so effectively every action is doing a linear scan of the filtered actions, implemented recursively. I'm pretty sure a hashmap would be more efficient, and would avoid inflating the stack so much too.
