If *immediate* is true, the queue is terminated immediately.
The queue is drained to be completely empty. The count of
unfinished tasks is reduced by the number drained but without calling
:meth:`~Queue.task_done`. All callers of :meth:`~Queue.join`
are unblocked even if the unfinished tasks is more than zero.
In addition, blocked callers of
:meth:`~Queue.get` are unblocked and will raise :exc:`ShutDown`.
The queue is drained to be completely empty. All callers of
:meth:`~Queue.join` are unblocked regardless of the number
of unfinished tasks. Blocked callers of :meth:`~Queue.get`
are unblocked and will raise :exc:`ShutDown` because the
queue is empty.

Use caution when using :meth:`~Queue.join` with *immediate* set
to true. This unblocks the join even when no work has been done
