-// Implements deferred ARC file system operations.
-//
-// When ARC is disabled or ARC has already booted, file system operations are
-// performed immediately. While ARC boot is under progress, file operations are
-// deferred until ARC boot finishes or the user disables ARC.
-//
-// This file system operation runner provides better UX when the user attempts
-// to perform file operations while ARC is booting. For example:
-//
-// - Media views are mounted in Files app soon after the user logs into
-//   the system. If the user attempts to open media views before ARC boots,
-//   a spinner is shown until file system gets ready because ReadDirectory
-//   operations are deferred.
-// - When an Android content URL is opened soon after the user logs into
-//   the system (because the user opened the tab before they logged out for
-//   instance), the tab keeps loading until ARC boot finishes, instead of
-//   failing immediately.
-//
-// All member functions must be called on the UI thread.
