+/**
+ * In this example, we start a web server with a cronjob setup to run every 19 seconds. The cron job sends a message "[INTERRUPTIBLE-SLEEP] Simulating cronjob execution.(case 1)" to the logs of the server container when executed.
+ *
+ * The problem with traditional cronjobs is that they don't get a chance to execute at a last time before the server
+ * shuts down. For example, if the cronjob is scheduled to run every 19 seconds, and the server is shutting down 15
+ * seconds after the last cronjob execution, then the cronjob will never get a chance to execute one more time before
+ * the server shuts down.
+ *
+ * In this example, we use Channel to schedule a cronjob to run every 19 seconds. The implementation allows the cronjob
+ * to execute one more time by checking if the Channel is closed when server shuts down.
+ *
+ * When running the following command to stop and restart the server, you will see the cronjob is executed one more time
+ * with message "[INTERRUPTIBLE-SLEEP] Simulating cronjob execution.(case 2)" logged in the logs of the server container:
+ *     docker compose exec -t server bash -c "supervisorctl restart interruptible-sleep"
