> The following code in runner.py:collect_update() may result in an infinite while loop when the provided timeout is passed as 0:
> {noformat}
>  while True:
>        ...
>         if timeout and total_time >= timeout:
>           break
>        ...
> {noformat}
> We have observed a case when the thermos runner gets stuck in a "deadlocked" state not reacting to SIGTERM with the last message in __main__.log as:
> {noformat}
> D0827 15:35:26.022495 30886 runner.py:856] Run loop: Work to be done within 0.0s
> {noformat}
