 * what would happen when PHP terminates the current transaction. This is most commonly used in command line scripts
 * that do some form of job queue processing. You would use this call at the end of processing a single job task, and
 * begin a new transaction (see below) when a new task is pulled off the queue.
 * Normally, when you end a transaction you want the metrics that have been gathered thus far to be recorded. However,
