If a call +- raises an exception then that exception will be raised when its value is +- retrieved from the iterator. +- +-.. method:: Executor.shutdown(wait=True) +- +- Signal the executor that it should free any resources that it is using when +- the currently pending futures are done executing. Calls to +- :meth:`Executor.submit` and :meth:`Executor.map` made after shutdown will +- raise :exc:`RuntimeError`. +- +- If *wait* is `True` then this method will not return until all the pending +- futures are done executing and the resources associated with the executor +- have been freed.

The second +- set, named "not_done", contains uncompleted futures. +- +- *timeout* can be used to control the maximum number of seconds to wait before +- returning. *timeout* can be an int or float. If *timeout* is not specified or +- ``None`` then there is no limit to the wait time. +- +- *return_when* indicates when this function should return.
