-// Implements a task queue that asynchronously executes tasks in a way that
-// guarantees that they're executed in FIFO order and that tasks never overlap.
-// Tasks may always execute on the same worker thread and they may not.
-// To DCHECK that tasks are executing on a known task queue, use IsCurrent().
-//
-// Here are some usage examples:
-//
-//   1) Asynchronously running a lambda:
-//
-//     class MyClass {
-//       ...
-//       TaskQueue queue_("MyQueue");
-//     };
-//
-//     void MyClass::StartWork() {
-//       queue_.PostTask([]() { Work(); });
-//     ...
-//
-//   2) Posting a custom task on a timer.  The task posts itself again after
-//      every running:
-//
-//     class TimerTask : public QueuedTask {
-//      public:
-//       TimerTask() {}
-//      private:
-//       bool Run() override {
-//         ++count_;
-//         TaskQueueBase::Current()->PostDelayedTask(
-//             absl::WrapUnique(this), 1000);
-//         // Ownership has been transferred to the next occurance,
-//         // so return false to prevent from being deleted now.
-//         return false;
-//       }
-//       int count_ = 0;
-//     };
-//     ...
-//     queue_.PostDelayedTask(std::make_unique<TimerTask>(), 1000);
-//
-// For more examples, see task_queue_unittests.cc.
-//
-// A note on destruction:
-//
-// When a TaskQueue is deleted, pending tasks will not be executed but they will
-// be deleted.  The deletion of tasks may happen asynchronously after the
-// TaskQueue itself has been deleted or it may happen synchronously while the
-// TaskQueue instance is being deleted.  This may vary from one OS to the next
-// so assumptions about lifetimes of pending tasks should not be made.
