Is my understanding correct that this is where cassandra is telling us it can't accomplish something within that timeout value -- as opposed to network timeout ? Where is it set ?

That's correct.  Basically, the coordinator sees that a replica has not responded (or can not respond) before hitting a timeout.  This is controlled by rpc_timeout_in_ms in cassandra.yaml.
