-    * Creates an executor service that runs each task in the thread that invokes {@code
-    * execute/submit}, as in {@link CallerRunsPolicy} This applies both to individually submitted
-    * tasks and to collections of tasks submitted via {@code invokeAll} or {@code invokeAny}. In the
-    * latter case, tasks will run serially on the calling thread. Tasks are run to completion before
-    * a {@code Future} is returned to the caller (unless the executor has been shutdown).
-    * 
-    * <p>
-    * Although all tasks are immediately executed in the thread that submitted the task, this
-    * {@code ExecutorService} imposes a small locking overhead on each task submission in order to
-    * implement shutdown and termination behavior.
-    * 
-    * <p>
-    * The implementation deviates from the {@code ExecutorService} specification with regards to the
-    * {@code shutdownNow} method. First, "best-effort" with regards to canceling running tasks is
-    * implemented as "no-effort". No interrupts or other attempts are made to stop threads executing
-    * tasks. Second, the returned list will always be empty, as any submitted task is considered to
-    * have started execution. This applies also to tasks given to {@code invokeAll} or {@code
-    * invokeAny} which are pending serial execution, even the subset of the tasks that have not yet
-    * started execution. It is unclear from the {@code ExecutorService} specification if these
-    * should be included, and it's much easier to implement the interpretation that they not be.
-    * Finally, a call to {@code shutdown} or {@code shutdownNow} may result in concurrent calls to
-    * {@code invokeAll/invokeAny} throwing RejectedExecutionException, although a subset of the
-    * tasks may already have been executed.
