+// The first sentence here is in contradiction with the current implementation:
 // 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.
