// Base implementation for platform-specific policy loaders. Together with the
// AsyncPolicyProvider, this base implementation takes care of the initial load,
// refreshing policies and object lifetime. Also if the object has
// |period_updates_| set to true it takes care of periodic reloads and watching
// file changes.
//
// All methods are invoked on the background |task_runner_|, including the
// destructor. The only exceptions are the constructor (which may be called on
// any thread), InitialLoad() which is called on the thread that owns the
// provider and the calls of Load() and LastModificationTime() during the
// initial load.
// Also, during tests the destructor may be called on the main thread.
