> For now 
> if the worker process does not exist any more 
> Supervisor will have to wait a few seconds for worker heartbeart timeout and restart worker .
> If supervisor knows the worker processid  and check if the process exists in the sync-processes thread ,may need less time to restart worker.
> 1: record worker process id in the worker local heartbeart 
> 2: in supervisor  sync-processes ,get process id from worker local heartbeat 
> and check if the process exits 
> 3: if not restart it immediately
