> 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.
