> Ideally, the NM should wait for a limited amount of time when it gets a
> shutdown signal for existing containers to complete and kill the containers (
> if we pick an aggressive approach ) after this time interval.
> For NMs which come up after an unclean shutdown, the NM should look through
> its directories for existing container.pids and try and kill an existing
> containers matching the pids found.
