> In streaming pipelines there are multiple calls to moveToOutputFiles 
> (https://github.com/apache/beam/blob/42984a821b3e73aee2966d11d7fb436b5ff22b68/sdks/java/core/src/main/java/org/apache/beam/sdk/io/WriteFiles.java#L796).
> When writing to GCS, this call uses executeBatches 
> (https://github.com/apache/beam/blob/279a05604b83a54e8e5a79e13d8761f94841f326/sdks/java/extensions/google-cloud-platform-core/src/main/java/org/apache/beam/sdk/util/GcsUtil.java#L551),
>  which wraps a thread pool in MoreExecutors.getExitingExecutorService(). This 
> wrapper introduces a DelayedShutdownHook which persists until the worker 
> exits.
