Pause for 5 seconds before dumping PerfMon results in postFinalize
This is a practical workaround to an issue that is observed in threads>0 jobs. In these jobs, if both ChronoStatSvc and PerfMonSvc are configured, ChronoStatSvc keeps dumping the results table after its finalize, even after issuing an SvcPostFinalize incident which causes PerfMonSvc's output to be garbled in the log file. With this MR we delay dumping PerfMonSvc results for 5 seconds to avoid this until the root cause of the problem is fixed properly.
Please note that I'm well aware that PerfMonSvc is not MT-safe and this is only for some trigger related tests w/ a single-thread job.
