PS1, Line 326:         closed_stream_expirations_.insert(
             :             make_pair(MonotonicMillis() + 
STREAM_EXPIRATION_TIME_MS, recvr_id));

It doesn't matter, closed_stream_expirations_ / closed_stream_cache_ only store 
the id of receiver and doesn't affect it's lifetime.

>From the sender's point of view removing the receiver from receiver_map_ and 
>cancelling it have similar effect, RPCs and scheduled deferred RPC 
>serializations become NOOP.
