WorkerLostError Handling

[Santifire92]

Hi, @auvipy !
I have a question, how can we handle this scenario where a worker gets lost abruptly like with a sigkill?
In the case of a timout i see you raise the exception so it gets propagated upwards but whit the worker lost it just gets catched and passes as nothing happened to the upper coordinator.

Can this be raised/what can i do?

	def mark_as_worker_lost(self, job, exitcode):
	try:
	raise WorkerLostError(
	'Worker exited prematurely: {0} Job: {1}.'.format(
	human_status(exitcode), job._job),
	)
	except WorkerLostError:
	job._set(None, (False, ExceptionInfo()))
	else: # pragma: no cover
	pass
