> When TS binary is launched with NO_REMOTE_MANAGEMENT flag (e.g., when launched not as a daemon but directly - this is extremely convenient for debugging), the PeriodicWakeup event is not scheduled.
> As a result, Log::flush_thread_main() does not wake up periodically, but only on log buffer overflow. Coupled with a horribly wrong activation check in Log::flush_thread_main():
> {code}
> if (now > last_time) {
>   if ((now % PERIODIC_TASKS_INTERVAL) == 0) {
>   // We run only when waken up at the moment which is exact
>   // multiple of PERIODIC_TASKS_INTERVAL!
> {code}
> this leads to that probability of any log output is low.
