class_docstr: A class for handling eager execution.
  
  The default behavior for asynchronous execution is to serialize all ops on
  a single thread. Having different `Executor` objects in different threads
  enables executing ops asynchronously in parallel:
  
  ```python
  def thread_function():
    executor = executor.Executor(enable_async=True):
    context.set_executor(executor)
  
  a = threading.Thread(target=thread_function)
  a.start()
  b = threading.Thread(target=thread_function)
  b.start()
  ```
code: def handle(self):
      return self._handle
