StartupTask;

// This class runs startup tasks. The tasks are either run immediately inline,
// or are queued one at a time on the UI thread's message loop. If the events
// are queued, UI events that are received during startup will be acted upon
// between startup tasks. The motivation for this is that, on targets where the
// UI is already started, it allows us to keep the UI responsive during startup.
//
// Note that this differs from a SingleThreadedTaskRunner in that there may be
// no opportunity to handle UI events between the tasks of a
// SingleThreadedTaskRunner.
