Tolga Ceylan e80a06937b fn: timeouts and container exists should stop slot queuing (#843)
1) in theory it may be possible for an exited container to
requeue a slot, close this gap by always setting fatal error
for a slot if a container has exited.
2) when a client request times out or cancelled (client
disconnect, etc.) the slot should not be allowed to be
requeued and container should terminate to avoid accidental
mixing of previous response into next.
