  * This class controls the different asynchronous states during our initialization:
  * 1. During startBackgroundTasks(), we'll kick off loading the library and yield the call stack.
  * 2. We may receive a onStart() / onStop() call any point after that, whether or not
  *    the library has been loaded.
