TaskQueue

implements
TaskQueueInterface
A task queue that executes tasks in a FIFO order.
This task queue class is used to settle promises asynchronously and
maintains a constant stack size. You can use the task queue asynchronously
by calling the run() function of the global task queue in an event loop.
