Shutdown newFixedThreadPool and newSingleThreadExecutor.

The javadoc of newFixedThreadPool says:
> The threads in the pool will exist until it is explicitly shutdown.

The javadoc of newSingleThreadExecutor says:
> Unlike the otherwise equivalent newFixedThreadPool(1) the returned
> executor is guaranteed not to be reconfigurable to use additional
> threads.
