Radosgw/Objecter behaviour for homeless session

Hi All, I have a query regarding objecter behaviour for homeless session. In situations when all OSDs containing copies (*let say replication 3*) of an object are down, the objecter assigns a homeless session (OSD=-1) to a client request. This request makes radosgw thread hang indefinitely as the data could never be served because all required OSDs are down. With multiple similar requests, all the radosgw threads gets exhausted and hanged indefinitely waiting for the OSDs to come up. This creates complete service unavailability as no rgw threads are present to process valid requests which could have been directed towards active PGs/OSDs. I think we should have behaviour in objecter or radosgw to terminate request and return early in case of a homeless session. Let me know your thoughts on this.
