From 8c59e64412881db8b9291c68bb49cdfa67e66586 Mon Sep 17 00:00:00 2001

Subject: Use a dedicated executor to run auto-gc in command line interface

WorkQueue uses daemon threads so auto-gc would not be executed after
short-lived commands run in command line. Hence use a dedicated executor
which we shutdown when the command finishes.
