Currently if client is abnormally down, and ServerOptions.idle_timeout_sec in server side is set properly, then the connection should be closed after idle_timeout_sec as expected.
But problem happens when server is abnormally down, client would never know this situation if the connection type is single or short with no timeout until next rpc is sent to broken servers. If the connection type is short with timeout, connection would be closed after timeout is reached. The last case is pooled connection, which may not be the problem since it is controlled by FLAGS_idle_timeout_second.
